I do the videos for our guild. Our first kills of each boss are at http://www.youtube.com/user/TheAtomicSquid
I'm usually holy, though there are a few HM Firelands kills I was disc or shadow. My guild is 10 man and fairly casual, but I'll upload as we kill stuff. I've got everything but Madness of Deathwing posted up there so far (so 7/8).
