I think TTRPGs should be unbalanced. Balance is a construct of games, and the fictional worlds the players will interact with are less immersive when everything is predictably tuned and equal. I think the fiction of a rogue being about as good as a fighter at combat is stupid. I think rust monsters and undead creatures that hurt your stats are way better than dire boars and skeletons who just shoot you with bows. I think that when rocks fall, things should die. These all contribute to the fantasy world seeming more dangerous, more 'real', like a spectral hand isn't shielding you from the worst the world has to offer.
I also recognize this is my dark fantasy bias yapping away
