What about limiting the selection of the ships for the different game modes?
That way, the gameplay could be directed in a certain direction.
And special maps for different game-modes are requireed. (Corporate War / Conquest need way bigger maps to allow strategic gameplay)
For example: (really for example! )
Anarchy -> Panzer, Torch, Wasp, Typhoon
Team-Anarchy -> Panzer, Torch, Wasp, Typhoon, Shaman
Survival -> Panzer, Torch, Wasp, Shaman, Typhoon
Miner Mayhem -> Panzer, Predator, Wasp, Torch, Typhoon,
Corporate War -> Wasp, Typhoon, Shaman, Auger, Goliath, Warlock
