Seems like while holding down left click ability sometimes when I press my quickslot skills they don’t actually activate and I have to hit the button 2 or 3 times for it to go off. Dying because your heal didn’t go off when you hit it just plain sucks.
AFAIK, if you are holding down ONE skill, nothing else should go off. It never does for me, I thought it was just part of the engine. I suggest doing as I do…Let the hell go, LOL.
