I just got Foolhardy Swagger tonight (Drunken Mastery level 26 Description = Taunts all opponents aroudn you to hit you for 5 hits) and I was so excited about it because my Sorc friend tends to get overzealous with her ae's. So we promptly went to try it out and the range is 0....and even when I _was_ on top of a single mob, (the range meter saying 0) It still didn't attack me for 5 hits, or even for one hit    

I think it has to "land" on the opponent you are targeting. I've gotten the same thing. It's similar in nature to Jeering kick. Has to land to turn the mob. I've had it work great, then sometimes, it doesn't work at all. It seems to work more times than not tho.
