We're on the same path kinda...
I've cleared some trash in MC with my 5 group at lvl 68 (3 shamans, mage, paladin) and it went well, the fire elementals spawn pretty quick though so needed more DPS from my crew to keep up with the spawns. Going back at 73(higher level and WAAAY better quest gear), see how far I can get then.
Not expecting to do any boss killing, but just doing trash mobs wich before took my 40 peope and now with 5 on my own is epic 8)

Good luck on both MC and Ony(BWL ?), as I'm up for the same personal task
