I have this 20 priest and a 20 mage. I already have a druid main who is resto/feral and want to play a dps caster for arenas/bg and heroics. I began this thinking I wanted to be pure dps, as I heal a lot on my druid. But then I thought of having the utility to heal would be cool. My buddy is leveling a warlock that I will be questing with 80% of the time. Any thoughts?
