ok ive tried DK+4druids and DK+druid+3Hunters to 80, but then i get a little bored when it comes to emblem farming.
So, trying something new, my team is underway, just instance/RAF boosting through to 60 atm so havent actually 'used' them yet:
Holy paladin = Tank&Healer
4x affliction warlocks = DPS

now, my crazy theory is, the paladin will mainly rely on healing himself for aggro.
the affliction spec warlocks have considerable self healing with haunt/lifetap/corruption which im hoping is enough to cover incidental damage and splash/aoe etc as i will have no group heal.
The holy paladin has quite a few damage reduction tricks and the locks have the pets for extra damage&utility.

My main concern is balancing defence & Spellpower on the paladin. apart from that i cant wait to see how it works out.
Im also hoping this team will prove viable for levelling in BG's part of the time, should be fun to try anyway.

Id appreciate any helpful feedback on my team choice? good or bad
