Just an idea, but I think it would be funny if in the future when you upgrade your character as far as it can go, your able to gain some sort of trait that sends fear into smaller enemies, Like the Grunts from the Halo series. If a level 35 (This doesn't exist yet, but its for the example) comes within 20 meters of a Level 3 Dreg, then that Dreg is filled with fear, and will evade you. I guess it would get annoying having everything run away from you, so the perk would be annoying, but I think it would be funny.
