I'm currently three-boxing a warrior, mage and priest in WoW. The priest mainly just heals and is specced Holy, though occasionally I'll respec to make her shadow just for kicks.

I was wondering if some other class would be better as a healbot in this little group. Particularly if it had better survivability. A Paladin comes to mind as maybe a good choice. Then I'd only have to worry about one squishie, the mage.

It seems priests have a lot of group healing abilities, but I find myself mostly just keeping the warrior alive. Would another class be better at single target healing and bring better utilities to the group than a priest?

Opinions?
