A little mentioned but great addition to the ranked system

Riot: [. . .] we’ll be upping the number of owned champions required to play ranked from 16 to 20.

I really think this will have a noticeable impact for newer players to League and help them gain some more skill on a variety of champions before jumping into Ranked.

Hell, it might even make Bronze a little more competitive for new players or normal draft players who want to try ranked out for the first time.
