I didn't take the chance to run Molten Core in beta - I don't recall if it was even open. Our guild is going to run it this weekend.
So did any of you run it? How is it tuned? Some of us are heroic dungeon geared, but we have a large group of slower levellers who are in the upper 90s and likely to be freshly dinged. Will it be too punishing if nearly half our group is somewhere just over a 600 item level?
