I am currently leveling 2 groups that I want to hit arenas with when I get to 80. One is a 4 mage group, and one is a 4 ele shammy group.

First of all, I would like to say thank you to many of the people that post on dual-boxing.com, I had no idea how to start multi-boxing before I found this site, and I have found so much good info here.

I was wondering if anyone that runs a 4 mage or 4 shammy setup has ever tried swapping out one of their chars for a hunter (or even a warrior I guess) for the healing debuff. I haven't seen many posts from people who are trying this, so I assume there is a reason not to do it, but I can't see why so any info would be appreciated.

Also I am currently planning on using a disc priest to heal (mostly for the shield and the aoe fear), but I have one of each kind of healer between 60-80 so if I have missed something and should be using a different kind of healer I would appreciate any info about that.

Ty in advance
