Well, I think that killing the six bosses I listed will leave only a little time to poke at Oregorger if the raid still ends at ~1400 EST. Gruul and H&F can be one-shot pretty easily, but the others will probably take a pull or two for everyone to see the mechanics and then kill on the second or third attempt. Oregorger, Blast Furnace, and Iron Maidens are the major cockblocks.
Probably the huntard. I had hoped the DK's guild would go straight to heroic, but they wanted to clear normal once. In hindsight, it was probably for the best because even normal didn't go as smoothly as I would expect it to for a guild planning to do mythic.
