Achievement Crackdown

I want to be able to make the Wispcloak so very badly. I still need Halls of Lightning, Halls of Stone Utgarde Pinnacle and Occulus to get the Northrend Dungeonmaster achievement and train with the tailor trainer for the wispcloak. My druid Paganstix (going as the tank), hunter Frosta and priest Bloodyhealin' (going as shadow) were into helping so we decided on Halls of Lightning. We had to pug another dps paladin. I'd been through there on my hunter and it would prove to be challenging on the healing side of the coin. This same group (minus the pally) had tried a few nights earlier but the hunter and priest had to shut there systems down due to a lightning storm. Kind of ironic. Halls of Lightning, lightning strike - ya. Anyway, we got to the first boss and forgot the fight and we got dropped quick. Okay, I thought; don't panic. Every healer starts out this way. The pally dropped immediately and we managed to pick up a mage. I'd prefer the mage in here anyway. It took us quite a while to battle our way through to the very last boss. We wiped once more and one fight came down to me and just the mage. We got to last boss, Loken who throws a really nasty lightning a.o.e. and I was throwing heals like a mad man. Madagan, mad man. Interesting. Moving along. When he threw out the lightning 'spiders' you had to run away and then come back once the threat passed. It was a lot to do with running around and trying to stay within healing range. We wiped on the fight and only managed to get him down to half health. This was a leaning opportunity. The other priest (Bloodyhealin') came up with the idea of healing through the damage. On the next try I kept prayer and renew on the druid while we alternated circle of healing and prayer of mending. Nobody fell below 75% health with that strategy and we dropped the boss. I got the Halls of Lightning achievement and was once step closer to that cloak. I got a nice wand upgrade in there. That was the 2nd boss fight where I needed a little help but the healing skills are coming along nicely. Not bad for a priest who is used to melting faces.
