This list contains data from Diamond level Korean solo queue over the past month. Master and Challenger specific champion picks which had high win rates and would’ve made the list were not included because of the very low number of games played on these champions.
Champion Name Win Rate Games Played KDA
Janna 54.58% 36,938 3.78:1
Leona 52.43% 15,745 2.80:1
Sona 51.82% 6,909 2.95:1
Blitzcrank 51.69% 32,947 2.81:1
Morgana 50.46% 22,293 2.85:1
Champions like Annie, Zyra and Fiddlesticks weren’t include because they are often played in other roles and I wanted this list to be for “pure” support champions.
