Crossbows have the same armor effectiveness as bows right? So why would a crossbow be better against heavily armored targets? I rather attack twice with the bow and shred more of their armor than do a tiny bit of damage against their HP.
Also, against orcs I have to move my ranged units around a lot so their warriors don’t get any ideas to knock back one guy and go after them.
I think crossbows would have to be tweaked so they can make use of the berserk perk. Famed crossbows are probably also a lot better if they can literally one-shot any raider. Then again, famed war bows are probably even stronger.
