10man, 7/12 after ~8 hours (2 raid nights) including breaks and whatnot, given that the first night we raided without one of our main healers, and used an OS with a social DPS.
Hardest for us was probably Megaera and Council.

I don't doubt the difficulty, but we, for one, just cba to do these alt-thingies. Seems like a PITA.
