I hope they nerfed it. it was intended for TANKS to take it. THat's what makes this boss a challenge to do dps wise. If you cheese it through rogues like that, you are not doing as intended and good they got rid of it. Maybe now your dps need to be better by having tanks.
Though one would think that rogues get taunt through symbiosis for a reason. Obviously Blizz had intentions of us tanking SOMETHING at some point.
