I agree with this for the most part. The controls and abilities were VERY smooth in WoW. It definitely impacts my gameplay when I am clicking buttons frantically and nothing happens. I dont knows how many times I clicked Invincible and a few seconds later realized it never activated.
While this is not a deal breaker for me, it is a large issue and I REALLY hope it gets resolved soon. Other than the controls and the FPS issue I absolutely am having a blast with this game.
