Razer is sending out a challenge to anyone who dares to call themselves a professional DotA team. They are hosting what claims to be the largest DotA tournament in the history of the game, and with spots enough for 1,024 teams (that’s 5,120 players), that claim may stand. The prize pool of $30,000 dollars is going to be spread among the top 64 teams in the tournament but only the top 4 will receive the prize of 5 Razer Carcharias headsets each.
