Add a Champion Slider to Rune Pages
Riot's goal for this Season was clarity? Then I have the perfect idea!
Something that has irked me for a really long time now is that - if you enjoy theory crafting - you are either forced to play League of Excel-Sheets or test your ideas in custom-games in which case you have to deal with lots and lots of loading screens.
My solution for this? Add a Champion Slider to the rune pages! Select any Champion and see how his or her stats change with the runes you add. You could even evolve this Idea around the champions skills or passives (i.E. Cassiopeia's bonus ap or Azir's attack speed).
