I don't know where this talk is coming from, my Lord Scourge is fantastic for me. I am a tank so I just set him in his DPS stance and let him go to work while hold aggro. Mob is dead. Repeat.
For me it's just gear-related and my unwillingness to endure constant wipes/shell out for frequent repairs. Once the gear issue is resolved Doc will be spending a lot more time in the medbay
