Masteries

So I was sitting here creating some item builds and I had an idea. I think it would be pretty cool if you could have champion specific masteries like how you can have champ specific item builds. It just wouldn't be as tedious as it is now if there were champ specific pages. As it is now, before every game I change my masteries to fit the playstyle and champ that I'll be playing that game. Not sure if there's a specific reason for the cap on mastery pages, but this is just an idea. Interested to see if anyone else would like to have this too.
