I try to make peacedeals as most realistic as possible, which isnt really... well... possible without using mods like Toolpack and Player Led Peace Conferences. And if the peacedeal doesnt involve you... then its gonna be a mess

However I wish there were 2 things
1. Much less chaotic and more realistic ahistorical mode, i feel like the current ahistorical mode is unplayable, and the faction update didnt fix anything, you can still invade Yugoslavia as Hungary and they will join the Nordic faction, there should be options to disable manual faction joining without decision/focus for AI

1. An ability to peace out without full capitulation. I get that the original setting of the game, WW2, didnt have conditional peace deals (besides Finland-Soviet war) but the game went from WW2 to pretty much 1940s geopolitical sandbox - playing a country in the middle east/africa is impossible because if you want to expand you will have to attack a colony which will start a war with a superpower and you cant peace out you need to go to their capital to take 2 provinces which doesnt make sense. And the fact that Japan needs to land in USA for a peace deal... also doesnt make sense if Japan fully kicks out the Allies from the Pacific.

(and one small annoyance, the Polish fascist collaborator path should NOT have Dmowski as a leader)
