I have really enjoyed the game. The major problem with it is that there is no concrete endpoint. Without a final boss or dungeon or upgrade, I really have no motive to stop and reset. After all, what is the point of playing again as evil or a different class series if that doesn't have an end goal either.
I suggest as a top priority that some end challenge be added to the game, after which one can reset, perhaps with a starting bonus for finishing the challenge prior to the reset.
Good Game...well balanced and challenging. Only criticism I have is that the Leader Skills should be in reverse order. Dash is fairly useless, Napalm is a little better, and Airstrike is best.
