not true at all. Considering how easy 90% of the content in this game is, it wouldn't even matter. Most players don't even do the hardest content before its nerfed.
Sure you might make a build that is flat out stupid, but in a game with thousands of people to play with if you get pressured into doing something a certain way so that people aren't mean to you well, grow a spine.
I love the concept of MMOs, but ever since WoW mainstreamed them design is just about getting as many subs as possible. That usually means leaving out the parts of the game that make people mean to each other (player choice, player competition, difficulty). Which is funny because those are like... the very essence of a "game"
