To be fair, I like the idea of supply trains. In EU and CK2 armies live off by photosynthesis.
Yeah, they finally gave the armies proper logistics.
They need to port this to EUIV and CKII post-haste.
Would be cool if they make it so you can pillage enemy lands and take some food this way, while the enemy can take the food and scorch the land to deny you food and feed their own forces.
Hopefully this won't lead to exploits like sending 100k men armies into the deep desert with no penalties whatsoever.
Could lead to interesting dynamics too, like doing fast attacks without supply wagons, in order to secure enemy regions fast and start getting food from them. Or supplying sieged armies through the water.
