I wanted to use smaller unit sizes because the huge unit sizes just don't appeal to me. I know the hps on units scale down when you do this but I noticed the enemy tower defenses don't seem to during sieges.
With huge armies a single unit of high elf artillery can take out a castle tower with some ammo to spare. On medium sized armies one artillery unit doesn't cut it, by far. It seems the hps for the towers either don't scale down or they don't scale down correctly.
Is this intentional?
