From what it looks like they definitely changed it a bit. It seems to be a single target melee attack, 6 second cool down and whatnot. However the bluff check isn't going off when I hit an enemy. Only when I purposely miss, or jump above the mobs and use it as to not hit any of them, does the bluff check occur. When it does occur however, it seems to bluff most things in a normal cleave range. Can I get some other input from other people that have tested it at all?
