We did him yesterday, mc totally screwed us a couple of times. especially in the last phase. Mc followed by the bubble shields can be pretty nasty.
Mostly because 4 of our dps had fears... 2 war, 1 lock and 1 SP. So keep them on CD on mc platform and in the last phase. I don't know if the minor glyph that causes people to stand still while feared works, still have to try that option. For warriors switching to Defensive stance + shieldwall macro helps out ALOT in bubble phases as well as Defensive stance + die by the sword + enraged regeneration.
