The Kog'Maw Katarina synergy stats shown here demonstrate the areas of his gameplay that do better (or worse) when paired with Katarina, compared to his overall stats. Significant differences are areas of focus that highlight how his gameplay changes when paired with this other champion.
Overall, Kog'Maw sees a large worsening in his KDA (ratio of kills and assists to deaths) when paired with Katarina. His KDA fell from NaN to NaN. This decrease shows that Katarina helps Kog'Maw perform poorer in ranked League games. Yet, the small difference shows that this performance change is not very impactful.
When Kog'Maw tries to synergize with Katarina, he sees a barely noticable drop in his complete damage dealt. This may indicate that Katarina does not support by providing cover for him to dish out more damage or that her support also helps increase the match's duration. Similarly, when Kog'Maw is played together with Katarina on the same team, he usually scores many fewer killing sprees than when he plays on his own. This is contrasting evidence that he is worse when playing alongside Katarina.
Additionally, when Kog'Maw plays with Katarina on the same side, he often takes a little less damage than when he fights alone. Getting dealt not as much damage may mean that Katarina does a decent job of covering Kog'Maw in teamfights.
There is no top champion pairing for Kog'Maw that will no matter what be his top ally. However, Katarina is a very typical companion for Kog'Maw. By locking into the same side as Kog'Maw, she raises their win rate by 0.3% to 52.0%. This clearly indicates that there is not really a strong synergy between Kog'Maw and Katarina that allows them to perform stronger together than alone.
Katarina has a greater difficulty than Kog'Maw. That means you must be very careful when finding Katarina allies to go into battle on the same side as, as they will need a greater level of skill to fight well with you.
Fighting alongside, Kog'Maw players should expect to witness an overall large increase in your team’s ability to deal magic damage. Together, these two can deal quite a lot of AP type damage.
In contrast, by grouping Kog'Maw and Katarina together, you will not be providing your other allies enough support. We recommend you have other champs on your team that offsets this gap in this pairing's capabilities.
