We did it last night for the first time and after two or three pulls we killed it.
As our guild have not done it before 2.0 i can't compare but i am sure it is much easier then before however you still need people to pay attention and do what they are supposed to do.
Only real problem we had is with 6 healers and a lot of AoE healing required our tanks were getting wrecked. it might be that we did some mechanics wrong (i can't think of any).
with current gear 6 healers is just about right. We tried with 4 hears and it was hard on tanks and group. We had 2 more healers log in and join the group and it made it much easier.
22 man group. We had few good DPS and few good healers but on average i would say our DPS was OK.
I am sure if you get 8 healer and two tanks - then 14 DPS will be more then enough even if they are not tops dps.
It gets a bit messy at the end but we killed it:
