I have been healing on my pally. To be honest, it was mostly PVP, but then I have no idea why I decided to heal some heroics.
Pain and suffering. We wiped on a couple of bosses, mainly because I was an idiot, like the eye balls – I got stunned and died. Then on Jaina when we had an extra pack and then on Murozond…he was horribly hard.
I think we wiped about 4 times over 3 instances, so considering it was my first time not too bad?
I was having massive massive mana issues, once I get that sorted out it may be ok.
I then decided (insanely) to do an LFR as healer, with my Frosties. It was a horrific LFR, we wiped on trash and Morchok because of an idiot, but it went smoothly after that once we booted them out. I healed, badly, but I healed.
Overall I was most impressed that I was actually healing the twilight heroics. I didn’t think I could do it. I really didn’t. I guess the week of PVP healing really does help
