Been playing WoW since beta. Multi-glad rogue and warrior in TBC/wotlk - have been pretty casual after that. I actually prefer having less buttons, but those buttons I have need to be interesting and have mechanics that can reward skillful play. Currently, that is not really the case. I'm a big believer in not needing tons of abilities for skillful play - I hope Blizzard can figure out how to get there over the course of Legion.
