Okay, so I've never done this quest and I've tried to look it up on thottbot, wowwiki and wowhead. They're very elusive about where this all starts but looks like I might have to kill Domo in MC to get the hunter quest to start it all. Am I right? Can I get some help with this? I haven't done any of the old world raids apart from last night, and BRD I think.... don't remember much about it.

you are looking for Ancient Petrified Leaf. It's a drop from majordomo in molten core. this guy is generally killed just before ragnaros.

does this part require a full raid group? (or the 20 ppl like last night?)

We could do it with a much smaller group ... the guild was going to do it one night and the server crashed after we breezed through a boss or two. I don't remember whether there was another attempt.

Yup, we did finish it another night with Khros leading, I believe.

MC takes about a dozen or so people now depending on inebriation level and the ability of the raid leader to ignore it.

Is the number of people required directly proportional to inebriation level, or inversely proportional? Because the more drunks there are, the more fire power there is, but the harder the RL's job is...
