I did it with a prot pally, resto shaman, 3 elemental shamans.

I cleared to raggy and a DK mate joined in for the achievement. Could have done it without him.

I don`t care if I have to farm MC weekly for a long time. I want to get the faction to exalted anyway. Just like any other faction really. Even working on 5x loremaster but progress is slow lol.
