we can always recover troops, but that's not all in the game, you have other things to take care of, I'll give you an example, if the dev nerf the sale of the blacksmith shop, most would have something to do in peacetime, because they would lack denarios , the game has many possibilities, unfortunately players seek the greatest possible benefit and don't take advantage of the possibilities, trying to make an army of only one culture is more challenging than doing the best for everything, it's how I play and I like to do it.
Constant warfare will always impact troop level, both for player and AI, so peacetime sucks, no, it's needed to recover troops, but players are always going to be unhappy with the game mechanics, I I see complaints that go against what the game offers, radical changes will not be made, the enemy retaking your territory is completely understandable because you do the same, but the AI sucks for doing what you would. Every player has an experience in the game and will have an opinion, even if it is eloquent, this is important.
