We've done AOE in the fields just outside the Varka Silenos Outpost with fairly good success. We usually have 3-4 nukers, a BD, tank, puller (usually a dwarf), a couple of healers and a prophet. The mobs are upper 70's to low 80's and are pretty tough to kill. We haven't tried a melee AOE party there yet, but the nuker parties work ok.
