Rekkles is one of the most famous players from the EU that ever played the game. Recognized and respected all over the world.
9 official pentakills and almost 600 career games. Currently, playing for Fnatic in LEC.
I listed three of his worst and best KDA champions. (Granted, he has worse KDA with Urgot and Morgana, but he only played 1 game each on those champions. Also his highest KDA champion is actually Syndra with a KDA of 30. But he only played two games on her.)
