ToD is worth running, at least once. It's a fun raid. I think if any two of the Savage Dragon, Peter, and myself helped the other group, New Invasion won't be a problem. But if anything, just tell him to step in and pike it. He can go smooch and we'll get him flagged.
So that leaves 4 quests to do, plus three raids. Likely it will take a couple weeks; while we can get flagging done this week (assuming Reywind shows), it might take a bit to run all three raids. On the plus side, I think some of the others in our extended group might be willing to step in and fill out a raid group for all three.
