Here's what I'd like to see in AH as an arena configurable setting...
The ability to resupply bases to make them repair faster. Simply put, you could hop in a gooney or a troop gv and drive a load of either supplies or acks to *another* field.
Naturally, the gooney would have to land or the GV would have to stop and perhaps the supplies would have to be unloaded (i.e. 'fired')
The effect would be to either repair 1000 bomb-pounds of damage, or 'fix' two random acks.
And as an interesting alternative, by adding a 'supply' shack at bases you could cripple the ability of a field to launch resupply missions.
It might also be interesting if you could resupply other commodities as well (fuel, ammo, troops)
As an interesting variant, you could also make it so that capturing a field didn't automatically bring back all the ack. That way there'd be an incentive to fly a resupply to get the ack back up to 100%
Just a thought.

p.s. And this would work really well with a rail system. Hint hint.
