I agree for the most part, some compositions have players who just cannot multi-task 2 roles. Mainly healer's who DPS and heal.
I actually got some flak for being one of the Strongest Warriors on the parse for 929 Warrior DPS on AS1
People say i force my sch to heal me and he cant dps when in reality the WHM cannot solo heal without someone dieing. So the lack of SCH dmg from our weak whm allows me to play more aggressive... the 7:02 clear is my clear at 5600 Raid DPS
and the 7:10 Clear is 5765 dps... how is this possible?
