I think instead of all Aggressive mobs always attacking you it should run away from you when your a higher level from it or reach a certain level that's it so scared that it wouldn't dare to try to hurt you unless you attack it first like a normal rpg game would be like if your stronger then any monster and have an attack advantage before the enemy attacks you first and make's thing's easier if you have to go afk and you have no place to hide or be a higher lever of surface like a tree for example then the mob to not get hurt from it.
