i worked it out by liturally just watching the incomming XP, when i had a friend running with my locks in DM i wsa getting 18-35 xp a kill the mobs were the same level as me.

this was about 5-10 xp less than what i could kill outside of an instance on my own.

running RFK with my 5 chars now started 24x2 and 29x3(with alot of rested) and they are now 26x2 and 32x3, ill probably carry on running RFK for quite a while as the level 32 characters are getting about 82-100xp a kill which is more than the level 26 characters. im waiting for about level 34 with the last 2 before going GY and Lib i went there tonight but the mobs were too high for my priest to heal the damage output, the result was a wipe.

For anyone playing about with warlocks heres somthing you only need 1 warlock with shadow embrace talent, haveing multiple warlocks with it doesnt make it stack or add more affliction effects to the target.

Just wondering if anyone knew of a macro that i could put in with my drain life that would check to see if Nightfall proc was up, if so cast shadow bolt if not cast drain life?
