I was going to report this with the bug tracker but after tuleap failed to send me the activation email, i gave up. I will however, mention that I found a spot in booty bay where the bruisers will sometimes not aggro. I don't know why, and i will only say that it is right out in the open near the auctioneers on flat ground. I killed a few alliance there and the guards didn't bother me, i killed a few more and then suddenly they aggroed and gave me what i deserved.
A hunter found it with me and also wanted to report it but he didn't feel like using the bug tracker.
