Three bugs of illagers

1.Pillager always close to target when attacking, they needn't do this, because they can attack the target by shooting, not hitting, if they do this, they are easy to be attacked by iron golem or player with sword
2.Evoker can hurt illager beast with fangs, but the evoker's fangs won't hurt other illager normally, illager beast is a kind of illager too, so I think evoker shouldn't hurt illager beast
3.Pillager can only shoot one arrow even if their crossbow is enchanted "multishot"
