in the fourth age bookmark: give Sterkist Faermeglin (the grandson of Beorn of the Vales of Anduin) a son because he dies of old age as soon as the game starts and his dynasty goes extinct
I've come to the conclusion that the way things currently are, it is nigh-impossible for the Dwarves of Erebor to reconquer Moria / Khazad-Dûm. The garrison of First Hall is around 8.5 K without levies, and even under Dáin Ironfoot, with his 35 military, the Longbeards do not have enough troops to keep Moria under siege for the 3+ years it takes to reduce First Hall alone, let alone the other holdings (even if you exclude attrition by conquering a neighbouring province ahead of time, random evens will still reduce the besieging numbers). Under his successors, the Longbeards are lucky to get more than 6K troops total. Trying to boost your troops with Orcs from recently conquered provinces (before the purges complete), just means you'll have to break off the siege to crush the massive rebellions.
My suggestions:
• Allow more mercenaries for Erebor, like Dalesmen mercenaries.
• Event troops, which perhaps represent Dwarven volunteers from other realms, or Humans hired especially for the occasion.
• The above event should be triggered via a Decision.
Wouldn't the orcs be too weak if this would happen? I don't think they would starve, because of this. The orcs can feed themselves without the Dark Lord instructing them to do so. Gundabad doesn't seem to be that undisciplined, due to their leaders Bolg and Azog and there are for sure some other like them. Sauron might be the highest Command, but there are still the Lieutenants and Generals of the Armies, who administrate the most. And if only Mordor would be affectedPerhaps there should be a massive reduction in Orcs and other evil creatures whenever the Dark Lord falls due to lack of supplies, and a lack of a central controlling will keeping them from fighting among themselves. Especially when they have fallen and can't get up. This could be some kind of attrition event perhaps so that small isolated and well-supplied tribes might survive okay but large centralized armies and populations in inhospitable areas like Mordor would be devastated.
