Riot gives melee champions 20% higher base stats to compensate for 400% more range on ranged champs

If a ranged champion jungles they can stand at a sweetspot distance from where a camp spawns. If they have the Krug's stunbuff it will cause the monsters' targeting AI to fritz out, causing them to spin in circles rather than attacking. I can do a full jungle clear on Kog'Maw before my first back.

Clearly this is an example of how ranged champions have a higher skillcap to outplay their foes as opposed to the wet-noddle fights melee champions have in the jungle.
