Riot, We need an option on the Masteries page of our profiles to see what we gain from them

-title-

when we click on the Masteries tab in our profiles, and begin swapping through the different pages, give us a sidebar of some sort to show all the stats and special passives our Masteries give us.

Think of how it shows the stats on the right side of the rune page.

I feel like this option would help a lot when creating mastery trees.
