Pillagers at an outpost should take shifts during the night

living in an outpost is a tough life especially when there's a chance a player might decide to pay you a visit ! our brave crossbow-wielding illagers deserve a rest , don't you agree ? well that's where "Shifts" come in ! Every night half the pillagers return to the tower while the other half keep watch , just like how some outposts work in real life ! The resting pillagers can be awoken by any projectile such as arrows , snowballs , eggs etc or they may also wake up upon any mob entering the outpost. the next night, the other group rests and so on. when asleep, the pillagers close their eyes and emits a "Zzz" particle. this adds more realism and detail to the outposts.
