EU4 - Development Diary - 19th of March 2018

Good day all. As I threatened last week: We're releasing this week's EU4 Dev Diary a day early for all you out there who like to digest all the changes we make ahead of time. I myself am currently abroad at GDC in San Francisco, so I may be rather sluggish in answering questions, but no doubt @Trin Tragula and @Groogy will rise to the occasion.

###################
# AI
###################

# Diplomacy
- AI slightly more weights in neighbors that might declare on them in prewar power calculations.
- AI will now consider giving provinces to subject in peace even if they have vital interest on them.
- Made getting Friendly attitude from AI directly depend on opinion to a degree; this is an attempt to fix the bug that for unknown reasons made it very rare.
- AI overlord cancelling Tributary relation or being cancelled by overlord will have -1000 towards acceptance for the duration of the opinion modifier.
- Added explicit check to forbid AI from canceling Transfer trade power or Trade steering when an agreement to their benefit is in force, and they are not preparing war.
- Fixed ruler personality induced war declaration disclosures and added this to Babbling Buffoon and Malevolent personalities as well.
- Fixed AI acceptance modding for custom diplomatic actions.

# Economy
- AI will now use Statute in Restraint of Appeals decision under limited circumstances. AI with this decision active will never reject Anglicanism.
- AI is now aware of more types of diplomatic expenses when performing budget calculations, hence less likely to underestimate budget.
- Free Thinker and Scholar personality rulers are more likely to Knowledge share.
- An AI country maxed out on tech will no longer try to advance to higher tech (this was reducing late game performance and preventing it from e.g. developing provinces instead).
- AI is now more keen to repair unmothballed ships during peace if they have no loans.
- AI is now able to decrease tariffs (again?)
- Fixed AI increase in budget when rich, so it will spend more on army and navy if being very rich.
- AI is now much more likely to build force limit buildings.
- AI now deprioritizes building force limit/manpower/sailor buildings until they have built some economic buildings.
- AI can now destroy buildings to build better ones if out of building slots when they are rich.

# War
- Mostly undid "AI prefers to siege with 1 or 2 regs above minimum of limit" change unless fort level is one. It caused other issues currently too complex for AI to deal with.
- Capped number of days in a row an AI army will skip processing for during peace to 15 to avoid unresponsiveness when preparing war.
- Fixed AI massing on borders before declaring war (for immersion), if there isn't too high threat nearby.
- Trimmed down number of independent AI armies for countries with many regiments as this was being a performance drain.
- Tweaked non-tributary subjects declaring wars (colonial nations) to require a greater advantage, as to create fewer "overlord must rescue them" situations.
- Fixed issue where AI wouldn't merge many small transport fleets due to waiting for an admiral assignment it wouldn't decide to make anyway.
- AI made more likely to choose fort provinces as fleet bases to avoid easy capture.
- Added guard against AI launching doom stacking invasions into one province islands that already have enough troops (this works for any friendly units already arrived).
- AI will no longer use armies to explore when there are threats nearby said army.
- AI can now split their transport fleet when they feel safe about doing so and army to be transported is smaller than fleet.
- Fixed case where army would refuse to board transport because target location is held by enemy controller (really old code not making sense).
- Fixed exploration nations' AI splitting up most or all of their armies into 5k stacks due to reassigning conquistador.
- AI should be slightly more proactive against transports landing troops on their home shores.

- AI now keeps a home fleet consisting of warships that's not allowed to stray far from their home coast.
- Revised number of admirals the AI recruits.
- AI no longer unassigns admiral from fleet as soon as it leaves port to another fleet in port.
- AI considers maneuver more important than before when estimating navy power and admiral skill.
- Reduced willingness of AI to suicide navies that would enter battle early with a way too powerful enemy fleet because of expecting reinforcements.
- Probably fixed exiled armies with splinters stuck unable to reach their base due to gathering up.
- Fixed cause of fleets stuck waiting for 0 unit armies.
- AI will try to keep a minimum fraction of its armies at home rather than sending them abroad to fight. This is however constrained by its splitting logic.
- Invading AI army stuck and unable to path to departure port will now disband. This is less bad than tying up a large part of the AI's force (including freed splinters).
- Tried to make AI less adamant about transporting troops to own areas with little actual military threat, as well as diverting troops from areas with significant actual threat.
- AI slightly more likely to assign leaders to main armies rather than splinters, and especially than divisions.
- AI can now simultaneously invade with multiple armies in same area provided there are enough enemies there (rather than exclusively with one army at a time).
- Fixed major bug in region assignment system that made most assignments fantasy comparatively speaking.
- Fixed invasion splinter consolidation behavior.
- Tightened up AIs use of repairing fleets for transport (especially, it will no longer assign such a fleet and then let army sit frozen and wait for it to repair).

# Other
- Revisited exploration logic to make it work as intended w.r.t. not using entire fleet for it. AI will also stop exploring during war properly.
- AI regions are now different from geographic regions and are calculated to optimize AI, will hopefully help with idiot Mamluk AI.

1.25 England Update and Rule Britannia set sail tomorrow. Enjoy!
 
And with land maint increase it seems that mercspam will be even more pandemic that before.
Merc maintenance is based on normal land maintenance modifier, so increasing it will increase merc cost as well. The change however was done to try and deal with the excessive surplus of money in end game independently of merc spam or standing army. This change was done together with also decreasing the various money increase you get from tech over time.
 
- Reworked how gold is demanded in peace offers: 5 war score now equal one loan size of target, and maximum WS on gold is 25.

Now THIS is interesting. Can't wait to utilize and experiment around with this, if a bit of a strange change.
 
Just to clarify: I don't need Rule Britannia to get the Purple Phönix missions in the new missions system?

The wiki says merc-maintenance is independent from regular land maintenance modifiers only modified by it's own modifier "mercenary maintenance modifier". Is this outdated information or is the merc-maintenance always tied to land maintenance?

Quote: "Normal land maintenance doesn't have any impact on mercenary maintenance"


And on a last note:

I don't know how I feel about Rule Britannia being an Immersion pack. Most paid features are global gameplay mechanics. This is not what I would understand to be an Immersion pack as of the Paradox definition of it. It is more like a small expansion pack rather than an Immersion pack.
 
Is this list exhaustive, or have the current unique missions for other countries (for example BB/Prussia, Poland, etc) been folded into the new system too?

Current unique missions are incorporated as far as possible. This does include Poland, Brandenburg etc.
I will post an exhaustive list in a sec.

No

Ah sorry just similar terms melding together. If memory serves me right (was on hoi4 at the time) it was the tech increase of 1% each mil tech that we increased to 2%. And that should affect both mercenaries and normal units

edit: Yeah double checked, the increase to 2% was done on the tech, not the army maintenance modifier, so it will affect mercenaries as well.
 
In the new system the following tags have at least one dedicated free mission:

  • Yemeni Group Missions
  • Aragonese Missions
  • Asian Group Missions
  • Austrian Missions
  • Ayyubid Missions
  • Bavarian Missions
  • Bohemian Missions
  • Brandenburgian and Prussian Missions
  • Burgundian Missions
  • Byzantine Missions
  • Chinese Group Missions
  • Coptic Group Missions
  • Daimyo Group Missions
  • Danish Missions
  • Dutch Missions
  • English Missions
  • French Missions
  • Genoese Missions
  • Gujarati Missions
  • Lubeck Missions
  • High American Missions
  • Hungary Missions
  • Incan Missions
  • Japanese Missions
  • Korean Missions
  • Lithuanian Missions
  • Mamluk Missions
  • Manchu Missions
  • Mughal Missions
  • New World Native Missions
  • Omani Missions
  • Orissan Missions
  • Ottoman Missions
  • Papal Missions
  • Persian Missions
  • Polish Missions
  • Portuguese Missions
  • Scottish Missions
  • Spanish Missions
  • StyrianTyrol Missions
  • Swedish Missions
  • Tatar Group Missions
  • Timurid & Mughal Missions
  • USA Missions
  • Venetian Missions
  • Generic Missions
  • Generic European Missions
  • Russian Missions
  • African Group Missions
  • Aq Qoyunlu Missions
  • Arabian Group Missions

On top of this paid missions still exist for Purple Phoenix and will be added for Scotland, Irish Minors, England and Great Britain with the Rule Brittania DLC.

Ok, but this then is still a buff for mercenaries in the England update? Since:

"Reduced most permanent sources of land maintenance cost reduction."

Means that mercs are cheaper in the update than they were before in comparison to regular units? Or were the permanent merc-maintenance cost reductions (Admin ideas) nerfed too?
 
Are you able to post a list of all the countries with new ideas particularly the dutch, I don't believe all of the ideas were revealed yet although I may have missed a leak somewhere.
 
"- AI regions are now different from geographic regions and are calculated to optimize AI, will hopefully help with idiot Mamluk AI."

What do you mean, "idiot Mamluk AI" ?
 
No Administrative ideas weren't touched. The change was to reduce the -60% maintenance reduction of regulars that you could have as a base. Though we should probably look at reducing the mercenary maintenance as well.
 
@Trin Tragula Doesn't this drastically reduce the available mission options for minors and OPMs, therefore limiting their possibilities? If so, that would massively skew the game in favour of bigger nations again. I assume you will iterate here based on feedback in upcoming patches because that might seriously harm some regions.
 
While the expantion itself is very lackluster (I find anglicanism, coal, naval doctrine, and innovativeness very uninspired, undeveloped, and boring)(Also them not improving the parlament mechanic in a britain focused dlc makes me very disappointed). I am so happy about the free mission system overhaul and hopefully great naval ai improvement that I kinda feel obliged to pay anyway considering the time investment they must have made for the free features.

Tl:dr Dlc is shit in my opinion, but am exited for the free update, should I pay or should I not?
