If you define skill as pressing buttons in order, sure, but you probably also whine about button removal in WoD lowering the skill cap. Smashing out a rotation is not and has never been skillful. Padding, especially wasted dps like AoE on Klaxxi, isn't skill either.
Skill comes in via:
- kiting, trapping, what/when to tranq/silence... i.e. anything to help things not go to crap/recover from going to crap
- situational awareness and prediction
- focus management
