evaneshence

I noticed that when I'm hidden if my first attack is Assassins blade if i click the power once it will give run the full animation but not actually trigger or even show "miss". the power wont circle as if activating and it doesnt use endurance, or wait for recharge, and i can immediately click again and then it will actually trigger. I am aware that if the power "misses" then i wont be unhidden, but this doesn't even seem to be actually activation it just runs the animation.
