I'm unsure on what enemies we'll be fighting, but since I'm under the impression that they might burst in through the wall during our breakfast, they'll be essentially bursting in on 4 benders, the masters of all 4 elements, and 2 pretty damn good swordsmen. So probably benders.

Or if we're timeskipping, then it's fair game for all of them. perhaps a mix, but with a majority of benders?
