Crossbow Accuracy Enchantment (Makes arrow fly exactly at crossbar aim)

Part of the thrill of Fps games is the fact that your weapon can be deadly with within seconds with precise aim, which requires skill.

This enchantment would make your crossbar smaller when holding your crossbow but make your shot extremely accurate to your crossbar placement, as well as make your arrow reach your opponent faster. 

The fact that your crossbar becomes smaller balances out the "overpowerness" of this enchantment, and will encourage more players to develop a new fighting style.
