The tank is wearing the Cata hardened obsidium set, but the others are mainly in Wrath gear.

What I had been hoping to do was to run one dungeon over and over since I don't have much experience in any of them. Then I'd be able to go for all of the achievments for that dungeon at the same time as many times as it took.

I guess now I'll just do them through the tool. Oh well.
