Watched the 3v3 ESL tourny yesterday. Apparently there's some bad blood between Kronovi (#1 player probably, part of #1 NA team, lives in Georgia), and Paschy (top 10 player, german) and De Boers (#2 player probably, also euro). They wanted to play with an American third (Gambit) in a North American event (there's Euro events and NA events), but got kicked out mid-tourny bc of Kronovi's protests.
ESL SPOILER
Also, there's some internet e-fight history between Paschy and Kronovi going back to Battle-Cars. Paschy was accused of boosting his leaderboard rank via playing his 2 accounts against each other.
