Add nerf to ground transports as part of GW

GW is already a very strong strategy, best at lategame on maps with not so many units (such as world map and Ancient). This is issue mostly on custom maps, especially Ancient.

On Ancient all units have at least +1 range compared to world map but cities are more crowded, making it really easy to expand. There is an unit called Carriage on Ancient and it has almost the same range as Air Transport on default map, but 350 cost and 10 capacity. Its stats are unchanged with GW. I think you don't need any more explanations to realize how OP is GW on Ancient with such a cheap transport.

Please nerf ground transports with GW.

This makes perfect sense. GW is outright overpowered on maps with good ground transport units, since it means that even those slow secondary defence units can expand extremely cash-efficiently, especially if there's enough money to buy ground stealths as well.

I concur to some extend, Carriage should be considered as an AT on Ancient and be more expensive for GW
