Speaking from personal experience being part of development teams for other MMOs (which I won't mention by name) I can say there were many times where as development, we would see one cookie-cutter build become popular and become "the only way to play", while the rest of us were rolling completely different builds and on lunch breaks saying things like, "What are they thinking?" "When do you think they will figure this out?".
To sum things up, I think there is still a lot we all have to learn.
