What about the 4 or so AOE circles he clusters around on the ground? How do you avoid those. As a marauder, I don't have the ability to get out of them that fast. And I take a good chunk of damage when they hit.
Did it this morning as a Jugg. When the AOE circles hit I actually got right underneath him in the center where the circles don't reach. Of course getting in position fast enough is a pain, but that's why we have Quinn.
