After months of 'Looking For Retard™' groups imploding on Galakras I finally managed to drop into a raid that managed to drop him on the 3rd attempt.
The group then went on and one or two shot Juggernaut and I think one shot Shaman which has already been a raid destroyer for me in the past.
Then we went onto Nazgrim and one or three shot him too.
Amazingly there was hardly any turn over of players and the tanks stayed the whole time.
I even got a couple of bits of loot, although there is still more for me in here [sad face]
