For what it's worth, Black Sorcerers casting Bane Fire should kill an Airqueen quite well, regardless of her defense.

Also for what it's worth, I would not join a game that said "no quitters" without taking my commitment very seriously. Like it or not, joining an MP game implies some sort of commitment to the other players. Usually it is a general commitment, such as "I will not cheat and I will try to play the game to the best of my ability." In this case, that commitment was explicit, and backing out of the commitment is pretty much a breach of contract. There is no legal penalty for the breach of contract, but there is definitely loss of face and respect within your community.

Having said that, it looks like you found a good solution.
