Use llamas to attack

Llamas are not really useful ,u can only use them for storage but that's it ,so I propose that you can use the llama to attack most knowingly spit at the enemy you right-click,longtap,push a button ,etc Even though you can't still control them you can atleast ride in them and shoot the spit. But there's a catch though. there's a cooldown you need to wait 3sec's to shoot again rather than use it like a machine gun.
