But with Blizz, more buttons does not mean more depth, it means more bloat. My main Wildstar class (engineer) had more depth than WoW ever has, and it only had 6 abilities total at a time (off the top of my head) because of the passives.
I would agree with you, but Blizz has shown that it can not do depth. Do we really need bloat just because the developers can’t come up with an interesting mechanic that doesn’t require double digit abilities just for the basic rotation?
