Last night I received a whisper asking me to heal Seth Halls. I told the person sure and informed him that I was Feral Spec'd with +630 healing gear in case he wished to find someone else. He didn't. So we're running through the instance with a druid tank, a paladin, a rogue, and a hunter and I'm healing. I basically used rejuv and life bloom throwing out a regrowth or HT if needed. Everything went pretty well, upto the last boss the only time someone died it was me and once the paladin. The point is the tank didn't die. Anyway we get to the last boss and the leader asked if everyone knew the fight. I said no because this was my first run through SH. I'm told the boss throws out arcane blasts that will easily kill you, so I should duck behind a piller when he's about to fire one off. I first time he did this I didn't move fast enough and died. We wiped, my fault. Then we wiped two more times. After the first wipe the tank noticed that I was Feral spec'd and commented on it. After the second wipe he quit the group and we got an Orc Warrior to come in to tank. After the third wipe the Orc warrior switched out to his healing paladin and I tanked. We easily finished off the last boss at that point.
So my question is this: Is there a trick to healing during the last boss fight? Because we made it through the rest of the instance with little to no trouble I figure my healing gear and style were ok. I logged out in my Feral gear so looking at my armory profile won't help. Any advice would be appreciated.
Thanks,
Hakana
