Yasuo and Riven need to trade ultimates.

Now, stay with me, because this might seem like the craziest idea ever, but I honestly think a really good solution to these two would be if they swapped their ultimates in their kits, because each has what the other wants...

This is not meant to exchange Riven's sword summoning or anything like that btw, she'd obviously keep her broken blade theme.

Riven is meant to be a low-cd fighter with an ability-combo focus. She would absolutely love a CC ultimate that refreshes her shield and puts her in the middle of the fight, while granting her bonus armor penetration for being there. It comboing from knock ups is only icing on the cake.

Meanwhile Yasuo is meant to be swift, pick off people, and more play the role of assassin and skirmisher. Riven's Wind Slash is a ranged execute ability that can fire off very quickly, and would naturally flow with Yasuo's swift movements. He doesn't need a bunch of bonuses for remaining in a fight, let alone a refreshing shield, because he's, by nature of his classes, meant to quickly get in, stick to a target and kill them, then get out.

If we swapped these two ultimates, it would put Riven and Yasuo both in better positions to fulfill there roles, while removing their more obscene problems, such as Riven having too much front-loaded damage to act as just a fighter.
