My guild is clearing through domo in MC in about 5 hours now. We're trying to get it under 4 hours so we don't have to split it into 2 nights. We aren't even trying rag yet, too many people with too little fire resist.
We've beaten all 5 aspects in ZG, but never in the same 3 day period, so we haven't attempted Hakkar yet. Bat, spider, raptor, and snake bosses go down the first time every time. Panther and tiger still give us a lot of problems, but usually because there aren't enough people interested in ZG to get the proper class balance. Once we got most of MC on farm status, people stopped caring about ZG. Same thing with Onyxia, we can take her down if enough people show up.
We've only done AQ20 a few times, and never very seriously. The first boss goes down easy, but people usually give up after a few attempts at that annoying second boss event (with all the waves of crap).
I don't really like raiding at all, so my shaman main stays parked except to do MC. I hardly ever get to do ZG because they usually run it late on weeknights, and my job doesn't permit my joining them.
So in a nutshell, I'm getting epics now, but I don't really get to use them because all I have time for is raiding and I had to respec to a stupid pve build that sucks for solo play and pvp. Whee!
