Im a 526 MW Monk, got the title on the 21st, my item lvl then (not that it matters) was like 522...took me about 100 tries, up all night - i was determined to get it...what pissed me off was that the mage always likes to just dps from a distance, then go into melee, and get the debuff you have to dispel, along with the tank or rogue, which is bull!@#$...the mage should be out back, not in melee range...all in all, i think i was just plain lucky to get it, the npcs were retarded.
Yeah. I think this is the part that makes the bubble phase so RNGy. It isn't a big deal who gets the debuffs, you just have to hope you don't get two bubbles in melee range, while the mage is slapping mobs with her staff.
