"But targeting an empty turret, and still be able to shadowstep... I didnt even know that was possible."
this.
I am a rogue and my common sense told me that I would be able to ShS only if somone is controlling the turret.
I had this question in mind but since I was mutilate spec (who doesn't? thesedays) I was too lazy to respec just to find out whether empty turret would still execute ShS
Thanks for contributing. +rep
Too bad it's a repost of a good post though (with SS and more explanation) =/
