There are a few ways I think that coalitions can be fixed. And to clarify my point, I don't think removing them is a solution. Even though coalitions are not very historical, they are important for game play balance and I do agree that it's an improvement over the bad boy system in EU3. Here are some ways to fix them:
- lesser impact of AE. It's too much right now. Coalitions didn't form in history after every war where territory is gained.
While I agree that the way a single peace treaty (it is the terms of the treaty not the war itself) can _seemingly_ fling half-dozen countries from a state of calm neutrality into hysterical alarm seems a bit excessive, I also do not think the player needs to be given 'a longer leash.' With enough diplomats, gifts, proclamations of guarantee, etc., one can often dissipate a coalition pretty quickly.
- AE shouldn't necessarily affect at all countries who like you, or hate the other country.
In fact, it does work this way already, more-or-less.
- When a coalition is formed against you, it should only activate if you declare war on ANYONE in that region (not just a coalition member), and should NEVER activate if they attack you.
I think this would actually be worse than it is right now. If you have moderate to low AE, this is already how it works. Taking away the possibility of offensive coalition wars for players that have really high AE does not seem to be an improvement. I think players need to play ALOT, and tinker with different permutations of actions to really see how variable and graded the AE->Coalition->Coalition dissolution-else-war tends to play out.
I have been playing and replaying a lot as France, in part so replays will be comparable but also just because it is a fun position. I have seen myself the brunt of huge unstoppable coalitions (because I conquered like a madman, i.e., the way it is done in most grand strategy games). I have seen myself the target of smallish, piddly coalitions that I beat (because the targets I picked on were their buddies, but inconsequential to the big boys). I have seen myself the target of many 'half-hearted' or quickly dissolved coalitions that I either actively undermined with diplomacy or peaceful activity. In sum, the current system, while not perfect, is already very 'well-tuned' to account for things like relationships, distance, etc.
ADDIT: though I have zero experience with how they fail to function sensibly in late game. I understand there is a 100-province threshold after which coalitions are just stupidly common. I believe you guys that that is a problem and thankfully it sounds like PI intends to fix it in the 1.4 patch.
- there should maybe be different coalitions for each continent, and AE is kept separate for each one. For example, if you're too aggressive in europe, only nations that have a presence in europe can join it. Likewise, if you're too aggressive in the Americas, countries that have no presence there shouldn't care at all, but nations there (natives or colonial powers) should care and join a coalition there. I always thought it's silly to have a native american or far east asian nation join a european coalition war that has nothing to do with them.
In several of the wars in this era, allies on farflung continents were technically involved, and in some cases literally involved in "European" wars. So while it does seem silly, it isn't completely silly.
To me, the main problems with coalitions are:
1. They are too solidary. It should still be possible to 'whittle' them down by peacing out smaller members one by one, just as one would do if engaged in a non-coalition war against one large enemy and several smaller enemies. The inability to negotiate separate peace with coaltion members I think is a major problem, although reportedly when it has been modded in it makes the whole system not work right.
2. Coalitions are a complete "freeby" for the coalition members. There should be some sort of 'burden' for being in a coaltion, and certainly some sort of cost or at least risk involved in it being defeated if not dissolved.
3. Defeating a coalition at present is quite anticlimactic. It needs to have some sort of 'reward' apart from simply winning.
