He murdered me as long as I tried to keep attacking him.
Finally, i figured I'd just go straight def. His gestalt gauge will ride with successful buffing, and sentinel powers. So just buff up, have a sent, keep yourself healed, debuff him a bit, then switch to like rav/com/med or com/med/com or whatever, and try whittling away.
I only just made it under the doom timer, but once his gestalt gauge starts getting close just keep hitting "x" and pray. That's what I did
