Champion Mastery

Is anybody else getting the sense that champion mastery is a good idea, but Riot could have and should have done so much more with it? All you have to do to "master a champion" is play a lot of games on it. My baby brother could master thresh if he wanted to and well it shows nothing. I think there should be a plaque for kda achieved, and things like win %. It just seems a little bit dry to me. Why call it champion mastery if there is nothing hard to it all and people just have to play a lot of games to "master" a certain champion. Also I think that once you reach a certain number of points you should get a skin for that champ that you haven't yet unlocked. Anybody else have ideas on this? Or am I the only person that cares.
