One problem is that the current terrain can only handle water at zero feet, which sort of rules out a dam. Also the MA terrains would have to be redesigned if you wanted to use this feature outside of a scenario, or rather the scenario. Seems like too much work for too little gain to me.
I would like to see a lot more variation in ordnance though. Fusing delays, different types of bombs like armour piercing, high capacity, cluster bombs and so on. Also different AP or HE heads for rockets and the ability to alter ammo belt mixes. The long rumoured perk ordnance system would be nice too.
