So I was just reading something hilarious in reddit about being THAT GUY, the only one that really made me wonder is the one about the dude who knocks everything back whenever the skill is off CD.
I play MCH a lot these days, and my approach to Blank is to wait until tank has aggro on a pack, pick the thing that's not the primary target, Blank it and bind it. Tank takes less damage, healer can DPS more and by the time our primary target is dead the bind wears off and the mob rejoins the pack. Everyone's happy, right?
Chime in, people. I don't want to be that guy annoying all the tanks and melees.
