Is it true the Princess spawns adds based om her HP (only seen one person say it) thus add control would be easier if everyone stopped damaging her killed the adds then went back to it
This boss is pretty easy and you can do it in different ways without any problems. Kiting adds works as well as killing adds. If DDs aren't geared good enough it might be easier to let the healer just kite the adds around the room.
WHM kiting is by far the fastest and easiest way to beat this boss. WHM need to grab as much hate before the adds pop, then use Sprint, kiting around while dps concentrate on the princess.
