I'd raid everything I could, 10 mans, 25 mans, 40's, panties, you name it.
So many achieves I need, I'd try to get them all in one day. Funny thing, if there were others, I am sure they would join me.
For what its worth, Full House (ICC 10/25) is a tough one...still ain't got that, even at level 85. Don't think I will ever get it less we go 3 tank, 3 heals, 4 DPS.
