Winning Percentage: 50.09%
Kog may be the most surprising entrant on the list, a character that was once considered a very strong champ, and still has a slight winning percentage. Yet Kog suffers from not excelling as either an AD or AP carry, and having relatively weak skills. He is better suited as a secondary source of damage, rather than a carry; which doesn’t leave him with a good place in most teams.
