Riot, what are you going to do with fringe cases like Riven?

Honestly, I like how there's literally no keystone for Riven. Obviously, she's not the only champion. But this new rune system has been out for over half a year already and we haven't gotten all champions on even ground yet. Are you guys even looking into this? It'd be nice to get some insight on champs who have literally no keystone for their playstyles and how others are abusing every single keystone you think could work for a certain champ, so much better that it makes the champ much more difficult to succeed with.

I know the boards have a raging hard on for Riven and others like her, but she's honestly in an awkward spot and feels very unsatisfying to play.
