The stats shown here emphasize several important Kayn versus Nami counter stats that may help us interpret the differences and similarities between the two. Kayn’s KDA ratio ([kills + assists] / deaths) of NaN is greater than Nami’s ratio of NaN, showing that Kayn may be more central to his team's team fighting capacity than Nami. This observation is in large part caused by the difference in kills.
Kayn usually has a much larger longest kill spree than his opponent does. Typically, he receives more damage than Nami. This is usually reflective of different amounts of tankyness, yet it can also imply that the champion with increased HP has less mobility and thus is not able to escape additional damage when engaged or poked.
Both League of Legends champs are great champions. Both have their strengths, weaknesses, and counters. In the game's current meta, Kayn usually fairs equally well when taking on Nami, with a 49.8% win rate. As a result, Kayn makes an ok counter for Nami.
While Kayn does have a lower winrate compared to Nami, when they face off with one another, Kayn also has a much greater difficulty level that makes him a more complex champion to pick up and master. You should be careful when picking Kayn into Namias his relative depth means you may not be able to unleash his full potential without a lot of practice beforehand.
Additionally, Kayn has only a small amount of utility and CC, a similar amount to Nami. This often makes her just as valuable during teamfights, especially when trying to counter champions with a lot of burst damage.
While there isn't one best champion for every situation in League of Legends, in Kayn vs Nami matchups, Nami is the better champ with a similar win rate, more champion depth, and a similar amount of utility to help out your teammates during team fights.
Kayn is a somewhat poor counter to Nami. Make sure you focus your gameplay on maximizing your gold and cs and clearing objectives. If you can do that, you should be able to stand on your own as Kayn against Nami.
If you would like to truly master Kayn to counter Nami during both the laning and mid / late game phases of League of Legends, you should continue reading to pick up a few extra lessons on this matchup. If you mind the build and tips displayed above, you should grow your win rate significantly and be that much closer to League of Legends pro players.
Kayn often accumulates a similar amount of CS relative to Nami. Champs who typically don't get many minion kills usualy don't need much CS to be effective, such as sup champs. They are capable of scaling properly off of their skills, stats, and first items alone. Yet, champs with large amounts of CS, such as hyper-carries, usually have to have many items to be effective. In either situation, try to exceed the numbers shown here to do well.
The top items to focus on in your Kayn versus Nami build include Youmuu's Ghostblade, Axiom Arc, and Profane Hydra. When Kayn bought at least these three pieces in his build, he performed much better when fighting Nami than with many other commonly used counter builds. In fact, Kayn boasted an average winrate of 49.8% when playing against Nami with these items in his kit.
