So, uh, they don't aim at targets.
What do I mean by that? I'm glad you asked!

They aim about half a player's height ABOVE their target, no matter what the target is, and no matter how tall their target, they will always aim about half a human's height over the target's center mass. This applies to ALL the NPCs, and they only get kills through their average proficiency on spawn, aka, ♥♥♥♥ aim and spread control. The issue is, this makes their fights... unsatisfactory, because they're not even aiming at each other, but rather consistently above each other.

This isn't a problem with VJ base either, I assure you, because these idiots are the only NPCs on the workshop that I could find who can't aim their ♥♥♥♥♥♥♥♥ guns, regardless of base, weapon, origin, etcetera. However the hell these guys have had their aimpoint coded, it's absolutely RUINED by the fact that no matter how good their aim is, they aim way above their target consistently.
Just spawn an enemy one, and stand still. Not a single bullet will hit you. They'll all whizz past your head. ANY enemy. Even the bazooka dudes. Come on, man.
