I worked hard to get my priest to 85 because they said healing was going to be fun again but after healing many instances I felt inadequate and useless mostly. I have enough manna to get through about 2/3 of the battles and that was only when I casted a heal every 5 to 10 seconds. I found myself missing out on all the action as I can hardly enjoy myself or I'll be out of manna again. I have all these new spells but I can't use them and I'm sorry but that is not fun to me! I need action, something to do other then watch everyone else have fun.
I threw in the towel on my priest and leveled my Paladin to 85 to have him destroyed by the Pally nerf. The dungeon finder Queues are 45 minutes to an hour as DPS and well I have better things to do then stare at my screen for 45 min waiting for a group only to have it fall apart because the healers and tanks keep quitting. I used to be able to do 12k single target DPS on my Paladin and now I'm lucky if I can get 6k dps.
I started playing TF2 again, it's so cool how I can just log in and have a Blast... I don't have to wait an hour!
