isn't the problem less the powercreep and more the existence of new bosses that completely fuck over everything but very specific strategies? powercreep in genshin isn't usually pushing units out of viability entirely, but having multiple bosses that go "fuck you" unless you bring a specific team comp is going to fuck over anything not of that team comp whenever one of those bosses shows up
also difficulty 6 stygian assault is going to murder all of us
