A suggestion for the mastery system.

Could we have a feature where we can select Masteries for specific champions? I mean, you pre set a specfic mastery page for a specific champion, and every time you choose that champion, that mastery page will be pre-set (but you can change it in the moment if you wish). Just so the "Forgot to change masteries" thing doesnt happen.

Last match it happened to me, i forgot to change masteries and it practically cost me the game. So itd be nice if we had that.
