When Yasuo plays on the same team as Kai'Sa, he sees a little drop in his complete damage output. This could demonstrate that Kai'Sa doesn't help protection for him to deal more damage or that her support also helps increase the game's duration.

This is contrasting evidence that he is worse when playing with Kai'Sa.
