I've just re-rolled a healer too, its good fun really..levelling her through the dungeon finder too which means i can stay as a holy priest from the get go.
My main is a tank and thats still my preference, but healing is a good alternative..shes at 46 at the moment so a way to go yet! My main is progressing through ICC at the moment, aiming for a LK kill on 10 + 25 before the expansion hits, but as i'm pugging everything its a pain in the backside..getting there though
I've tried levelling 2 DPS toons but its just so incredibly dull and boring..pew pew is fun for a few levels but then it just gets dull and repetitive, you don't have to react and think the same was as a tank or healer. I'm keeping on with them (mage + loladin) in the hope that it gets more fun at level 80..but focus will be on my tank and healer I think, thats where my heart is!
I've been running the brewfest boss with my tank, but bit frustrating that the drops are so poor, all ilevel 200 stuff apart from that single 266 boe and the mounts. I've got the kodo mount now so really just after the other one..I wish blizz had at least included 1 264 trinket to give us something to aim for after the mounts drop.
