As of now, normal ballistas are better than trebuchets for sieging. They're quicker to reload and damage just the same. Trebuchets, however, take a long time to reload and they do the same damage as ballistas. They are also not a big threat to siege weapons like ballistas are, making trebuchets absolutely useless.
I think damage for stone trebuchets should be boosted to 4000 and fire/ice trebuchets boosted to 3000, with slightly increased damage vs. siege weapons.
