Not all the way to lich king, but I'm still playing, and raiding. My guild has 7 bosses down on 25 man, and my 10 man group has 8 down. The guild isn't that great, but I can slack off and not have to meet the ridiculous requirements that I'd have to in a more hardcore guild. For example, we don't even keep track of attendance. In a hardcore guild, 1 or 2 days missed would put me in a lower attendance bracket and I'd get passed up for gear.
