Your gear is not insane any more, if we were still in patch 2.3 then you would be pretty good. Chances are you only got your t6 because you were carried, bought it, its scammed, or your guild finally got to see endgame because the atunement nerf.
Step your helm up from illidan to kil'jeaden. And get out of here with the "oh im 8/8" no one cares, full t6 is garbage. WTB 3rd set bonus.
