5x Shamans + 2x ???

I have my 5boxing shaman setup working and getting them geared out. I've also RAF'd two new accounts to level new 4 man teams with RAF bonuses. This means I have two extra accounts that I can have toons on that can run around with my shamans. I was thinking along having 2x mages to aoe people that come in on my team but also having a priest or lock to AOE fear people off my team would be nice. Can a COH priest aoe heal people out of his group? Obviously this is strictly an idea for goofing off in bg's.

What are other people's thoughts on this? There is a good chance I will never end up doing this but I still would like to theorycraft it out!

CoH heals 5 people max...the person you target and the people in range in that target's party. Kind of like a ranged prayer of healing :)

Ahh, thanks for the info. Anyone else have any suggestions?
