So, the game has been more fun then I've ever had in 3 years in online play. However, it seems completing maps and objectives is pretty quick in multiplayer and solo. So I think it's be great to have a more where there's no real objective, no limit on balance points, etc etc.
Just a mode for x amount of people to bring whatever vehicle they want and muck around in what seams to be the true spirit of the game: mud running! There could even be options for the creator of the lobby to limit the vehicle selection to one specific vehicle or a couple vehicles only, or run what your brung where everyone can choose whatever they want. I think there could be a lot of possibilities to a mode like this.
