I think it would be dope to see the average KC a person has for each drop.
For example:
Average kc for Abyssal whip drop: 377
Average kc for Armadyl hilt drop: 638
Average kc for Uncut onyx drop: 666
Obviously if it requires a great amount of time to code etc, there's no need for it, but if it's pretty simple to code, it would be cool to see in the game.
