...Have you actually finished the game...? In The Final Act, things get very non-linear, and there are A TON of sidequests, a few of which require you to be extremely high level and -will- make you rip your hair out a few times. The only thing I object to is the fact that you need to do all the end-game sidequests at level 80+, meaning lots of grinding. The game is awesome except for that. (I haven't actually finished the game, I'm still trying to level myself to complete the optional areas)
