I two-manned this the other day. I had my level 72 prot pally go in with a level 80 discipline priest. It took FOREVER but we did fine - even when we got feared into the eggs a few times. It was the most boring hour that I've spent in an instance in a long time. I think the big thing for my being able to deal with it having the crafted cobalt gear from northrend. My priest kept me up and I did my best to hold the aggro and do a little dps. If you can craft your whole team the level 70ish blue gear from Northrend you should be fine. What classes were you running in there with?
