Very Easy. with DK, lock,mage,priest,huntard (year I still haven't lvled my shammy
Did 5/5 kills (no wipe)

Ahune handed me my arse, but this one is easy .

- Just park your toons at the short wall right of Coren with their back to the wall. (next to opening to the bar)
- Lay down DnD with DK
- talk to Coren with your alt and get the hell out of there

- let tank pick up agro
- DPS the shit out of him, forget about the adds.
- AoE Healspam, Prayer of Healing and Circle of Healing (macros see priest macro)

Done.

No mounts or remotes so far, but ...brew Trinkets which have 150 Stam Great for my tank
