my guild and some of our friends kept getting boss to last faze but we just been having horible luck with mcs right before the bubbles.
we had it down to 3% our best attempt would of had it if me the healer didn't get mced right before the bubbles and we were 2 healing.
then anther time it was going perpect we had mcs and we were getting in bubbles we were in them nope a mc knocked several of us out of bubble that fight really needs to remove mc from 4th faze it would be so much easer and less risky.
