AI Zombies, can only describe them as useless, but perhaps a way you could improve them is give them +0.15 walkspeed so they can move faster. Make them do 8 dmg per hit since they will be attacking you in horde's and are usually easy to die. And let them have a 5% chance to spawn with armour rarely like they spawn with a helmet that gives them like +10 HP or a vest
