I almost never release countries. This does hurt my TC through Partisans, but nothing I cannot usually handle. In my game as Germany, I control India, All of Europe that is not allied with me, and European Russia after the Bitter Peace event. Surprisingly, only Britain, France, and Russia have any Partisan activity, and Britain is being occupied by a force of about 25 divisions. Britain was my only major revolt risk, France and Russia both have 1.0% revolt risk and will soon be brought under control. The point is that it is completely possible to manage TC to not make it go through the roof, and, at least in my Vanilla Doomsday game, India never has any partisan activity when I take it. In the German game, they have absolutely no partisan activity
