Exactly this. I always spend most of the game post 1600s doing everything I can to avoid fighting coalitions, not because I can't beat them, but because it takes a stupid amount of time and effort for so little gain. I would have no problem with coalitions if we could actually extract concessions for winning the war proportional to the amount of effort it took (such as being able to peace treaty with individual coalition members), but it's just not worth fighting a world war for 2-4 provinces and 100 ducats.I think coalitions would be a cool endgame type threat if they were designed that way. But right now they seem designed only to punish you for your expansion. If you had warscore costs reduced based on the size of the coalition, at least a little, then there would be a risk-reward aspect. Right now, you fight this giant war against all of europe, and you get at most like four provinces out of the deal. It makes it so instead of massive wars during the endgame the smarter thing to do is look around for minors who haven't joined the doom-coalition yet that you can beat up.
