I did them with 3 people tonight. It was in NO WAY hard or difficult. For the Burial Caves we didn't have a way to heal... It was just as I feared in OB, no skill needed, just run through and spam aoe attacks. We had one guy who god love him, tried to tank... but I kept ripping agro in shadow form... But it was okay, since ego storm holds everything I was never in too much danger.

The bosses are not hard in the least. 400k HP, that's about it. I think I actually did yawn during the fights... And no loot either - only the quest rewards. But that's okay I guess, I wouldn't want to run them again anyway, too boring.

I'm seriously hoping Lairs have more to offer. If not, I think the devs need to go play WoW and Everquest/2 and Final Fantasy 11.
