The other night while healing Onyxia. My guild and I noticed I was bugged and that even Rank 1 Holy Light would pull Ony off the tank, (even after not healing for a good 4 minutes in phase 1, while many other Paladin and Druids were healing just fine). We determined that somehow my Righteous Fury was bugged, because even though I didn't have it on, my aggro was still as though it was. I tried to log out and back in, alt+f4, recasting and clicking it off, etc. But could not get the bug to disappear.
I posted the bug in game to a GM, but was told to come here and post it.
