Had an 8 man attempt on Noth with another boxer, with a similar setup to yours but having problems with the healer (priest) dying from aoe mobs or missed taunts. Have a couple of questions for you:

1) Do you have your mage set up to decurse the group, or are you just eating that damage?

2) It looks like you are trying to keep adds down to one or two before continuing to dps the boss - is this the case or are they mostly going down from incidental CL damage?
