Yeah, we reached the point where we just ignore the Adds now and focus the Wall itself down. That requires some real DPS though. As a Healer you can chip in with your DoTs or other extra dmg skills in between healing. I do it on my SCH all the time. I start the fight with applying all my DoTs and after each Repel I apply them again, cause healing wise the whole fight is a joke. With a SCH in group as Healer you want him to use Selene as well, to support the groups spell/skill speed to fasten things up even more.
