Overall, Rumble sees a very large drop in his KDA (ratio of kills and assists to deaths) when paired with Kai'Sa. His KDA worsened from NaN to NaN. This fall shows that Kai'Sa helps Rumble perform not as well in ranked LoL rounds. Yet, the small difference demonstrates that this performance change is not very impactful.
When Rumble is paired with Kai'Sa, he gets a barely noticable drop in his full damage dealt. This change could signal that Kai'Sa doesn't help protection for him to deal more damage or that her presence also helps increase the game's duration. Similarly, when Rumble is played alongside Kai'Sa on the same side, he usually scores many fewer killing sprees than when he plays on his own. This is contrasting evidence that he is worse when playing synergisticly with Kai'Sa.
Additionally, when Rumble plays with Kai'Sa on the same side, he typically receives a little less damage than when he plays alone. Getting dealt not as much damage could indicate that Kai'Sa does a decent job of covering Rumble during teamfights.
