I think they should do more with this. I don't think it would be totally fair for Superman, GL, Captain Marvel, WW (if she's in) to fly around the screen and almost be unhittable, but at the same time they use the ability to fly all the time when they fight opponents. I think it would be cool if some of the flying characters could fly/hover a few feet off the ground to do some moves instead of having to walk around all the time. Maybe, you could do a button combination to initiate the fly/hover off the ground and then fight like that until your opponent would hit you causing you to come back down to the ground again. It just kind of stupid to have major flying characters walking around on the ground. This could also apply to Raiden if/when he gets in.
