Right now, bow uses sharpness for increased projectile speed. The problem with this is that it seems to add extra damage (on my server, sharpness will let me kill a zombie pigman in one hit, while without it, it takes two). Please replace sharpness with projectile protection (making sense with some twisted/ironic logic?) or some other enchantment that doesn't have any effect on the bow normally.

Silly me, it's because bow damage is calculated through velocity.
