Hi,

Currently I'm quadboxing my mixed team, dwarf pala, human priest and 2x gnome mages.
Big fun, really big fun.
Have to agree with heffner, raising the mages their spellpower is a bit hard.
During leveling the priest was busy dealing damage, healing was almost not required.
Imagine running through packs of mobs, concentration, healing nova and 2x arcane explosion 8o
In instances the priest is healing only, maybe sometimes I'll let her cast a spell to push the mob over the edge.
