As many of you have seen in the League of Legends client, when you go to champion collection, choose a champion, and look under their overview tab, you will see a chart representing their abilities; specifically, the amount of Damage, Utility, Mobility, Crowd Control, and Toughness they have.

I assume these charts are based on their ability sets, as well as their growth ratios relating to those five traits. I wanted to see which champions have the most points on their chart as a whole. In a way, this proves who the most all-around useful champions in the game are. I thought I would share the results with you in an organized fashion.

Based on this data, one can argue that Rakan, Shen, and Aatrox are the the most useful champions in League right now (since they have a little of every trait, or a lot in multiple traits), whereas Miss Fortune and Kog'Maw are the least useful. I would like to state that Rek'Sai and Jarvan IV are the only two champions right now that are perfectly rounded in everything (not lacking or excelling in any one trait).
Edit: I color-coated them based on roles.
