One thing to keep in mind for topics like this (and we've seen this topic so many times already) is that alongside this we also have topics complaining that tanks don't know what they're doing, healers don't know how to heal and/or dps, DPS players don't know their rotations/how to AoE/etc.

So on one hand the game is too simple and easy and boring to play, but on the other hand the vast majority of the player base doesn't know what they're doing. If the game, according to some people, is already just too damn hard for the casuals to understand and you go and make it even harder, how are you planning to square that off?
