Interesting to see this with calculated numbers, but I guess if you roughly estimated it beforehand, you knew it before. The problem is, that esports in WoW doesnt get that much attention and you dont really get any benefit for organizing such a tournament. The majority of the viewers already play it anyway. Its just an entertainment thing.But its a big company, at least the minimum wage should be paid. I dont know about the circumstances of the players, but I dont think everybody is a fulltime streamer actually generating money for being in that tournament, e.g. with viewer gain and investing A LOT of training time.So even if its a financial loss for Blizz, they should spend that much for their pro leagues, that it wont happen that one of their players starves to death during a match or cant connect to the internet because the electricity bill couldnt be paid.
