Based on 141 recent matches analyzed, Dr. Mundo wins with a 51.8% win rate compared to Kayn's 48.2%, giving Dr. Mundo a 3.5 percentage point advantage. Dr. Mundo dominates at every stage — from early laning through late game team fights. This consistent advantage makes it difficult for Kayn players to find favorable windows, so team-dependent strategies and avoiding solo confrontations are essential.
