I root for SlayersBoxer because he got me interested in ESports.
I root for Kyrix because his play style as Zerg in Season 2 was the most fun I've had in the ladder.
I root for MMA because I love watching and want to emulate his late-game play style.
The list of Korean players I love and root for is far longer than the list of foreigner players that I love and root for.
However, apart for when he gets matched against SlayersBoxer, I will always root for Idra when he plays because he's the best that America's got for now.
