Phase 1, heal, heal, heal
Phase 2 - Onyxia's in flight!
SHADOWFORM
8 Priest blasting away at Onyxia in full on shadowform while shes in flight would be purepwnage.
Seriously, 250dps from 8 people = 2000dps z0mg!
not to mention the vampiric embrace healing each party, druids keep rejuv up and we're good to go.
just a though on my part, not like any of you bitches would ever go for this.
