Meaning nothing that'd require extensive art development, etc. No new GVs unless they're very minor changes to an already existing GV.
Fuel enabled, and realistic turret motoring:So GVs can only move their turret while the engine is off if they could in reality. It would make real tactics more viabe. Fuel is refilled by supply vehicles.. Perk reward for resupplying somehow corresponds to how scarce supplies are/have been to target GV. No perks if supplies used by enemy, obviously.
Is this feasible, with typical ranges in AH's GV world? A fuel multiplier could do it, otherwise.
Separate track controls:This would allow rotating in place. Real tanks could do it. Makes a really big difference.
It would need a couple of new commands: A torque invert button, and a brake button for each track. As it is we have plenty of room left in GV commands (e.g. the flight category has 4 times as many commands):
Remote turret controls:At least slave the turret to the driver seat's rudder. Otherwise, give a few dedicated commands to remotely turn the turret. Either left/right commands, or commands to move the turret to cardinal (relative to the chassis) positions. 4 or 8 positions.
And a switch to toggle slaving the pintle's heading to the turret.. As it is you sometimes come back to pintle from another position and find the pintle looking another direction from where you left it. It would be a nice option, it's not rare to miss shot opportunities because of this. It would probably be best as a three option choice: as it is now, or pintle fixed to its absolute (compass) heading, or fixed to relative to the chassis.
