Garen.
Just got to experience the full lethality build. While it is possible to counter I must say (and excuse my french) that it's fucking broken.
this is like playing against good ol' ap yi. no counter play, just unfair and unfun for an entire team.
also dynamic queue 4 man premade vs soloq team should be permantly removed from the game. Make the premade (more than 2) wait longer to play against other premade.
