So I have this guy, an 85 Pally, and an 85 Druid on Azjol and I'm going to transfer/faction change one of them to Zul'jin. Problem is, I have no clue which to pick and I'm not about to pay for all 3. I've looked at all the classes and their changes since Cata and they all still seem appealing. I wanted to try a little of everything like I did in Cata, Healing, DPS, and Tanking, in both PVE and PVP settings. (Obviously I can't heal on my DK, but that doesn't sway me from him.
I loved healing on my pally in Wrath but Cata ruined it for me so I made my druid. I enjoyed tanking on my pally and Prot seems as good as ever, I wasn't to keen on Ret in Cata and it seems to have taken a hit.
I liked Balance on my druid and felt more "in the fight" than my Lock (idk why). I loved healing on my druid too but had a lot of mana trouble in heroics during Cata (not sure if that changed in MoP) I never tried feral though =/.
I loved being DPS on my DK but wasn't the best tank, although I did enjoy it when I was doing well.
As for PVP, I didn't do a whole lot on my pally because it felt slow to me and I sucked. I liked it for both Balance and Resto, I tried feral while leveling but felt like I was betraying my Rogue >_<. And I enjoyed PVP on my DK no matter the spec (although I didn't do much, kinda just tested it out). PVP is the only time I like to stand back and cast on my Lock; just because if anyone gets to me I usually can't peel them and get beaten into the ground.
As you can see, I'm probably just being stupid and indecisive, but I'm still looking for some input that might sway me one way or another though obviously I haven't given a whole lot to go by.
