Improving Champion Mastery system

Current mechanism - match-making game rating, exp as in champion points, level-ing champion mastery

Thoughts and improvements - More stats included for champion mastery including Average Grade, Kills, Death, Assist, KTD, Time Spent, Games played

Reason - The current mechanism is not quite interesting as there's no specific champion stat tracking, the solely leveling mastery does not essentially mean anything. Basically saying the more or the longer you use that specific champion, the mastery level would eventually increase. The lack of micro-stat tracking makes the leveling pointless and lame. Even though Dota 2 does not have a detailed stat tracking in-game IF you choose not to pay a single penny, which in Dota 2 you can pay for socketing stat gems into gears and allows you to track different stat, even as specific as the damaged dealt by using a certain ability. Im not saying Dota 2 > LoL in any sense, but a more detailed tracking system is definitely more fulfilling as a summoner. Please provide any thoughts you have. We are trying to make LoL a even better game. Cheers
