I bet ever single one of you dream't of sky battles. To be able to have a duel with your friends while flying in dbo.
Well, almost all of you lost hope for that when dbo has shut down, and when Dbo Revelations has begun, all of you have just forgotten or just didin't care. Well this is an early suggestion. 'Why not add Sky battles?' and the possibility so fly in to the sky while your in a battle, it should not be that hard to implement(or just a little harder than it seems) since i have some experience of programming.
So yea this is my suggestion.
