Of all the female hyper-scaling duelists, Riven's kit feels the most outdated

These 4 champions are the reason I think I might never be able quit league. Despite all the balance issues surrounding the state of the game and a few name champions, Riot's newer reworks are still nonetheless incredible designs. Everything feels so fun and fulfilling to play.
Between these 4 ladies, Riven's kit is the hardest to master and also the riskiest. Sadly, it also feels the least rewarding to play regardless of how well you impact the game. What I wish is for Riot to modernise Riven's kit a bit.
I think it might have something to do with the utility each of the other three bring to the table. Even when behind, all three still have their ultimates to turn the game around. Riven's ultimate however, is simply a stat boost and therefore, a Riven that is behind is punished more severely.
I'd love for her kit to be more accessible and fluid for everyone at all ranks.
