Rito Pls Buff: The 10 Least Played Champions in LoL Season 4

10. Karthus

Games Played: 67,627

Games Won: 34,665

Games Lost: 32,962

Winning Percentage: 51.25%

Karthus’ ultimate is both much-loved (by his team) and much-maligned (by his opponents), and as you can see, he is rarely played despite a notable winning percentage of over 51%. Despite that, Karthus suffers from having only one real damage skill (his other is an aura skill), and building him requires all manner of attention paid to different stats, including his tankiness so he can get close with that aura and his short-range Q, and his cooldown so he can more often use that loved and maligned ult.
