Exactly, they are making money and putting half of it back into tournaments, how much do you think Blizzard have made over the years since they started with D2 and SC1 and how much have they put into tournaments or e-sports in general? Blizzard have gamers money yet what have they done with it? how much money has Blizzard and Activision made in the last 20 years from gamers money and how much have they put back into e-sports?
How many tournaments have Blizzard themselves or officially backed for any game they have created? never mind expansion packs, SC1 was one of the most popular games on the planet yet had like 1 or something didn't it? WC3:TFT didn't have any yet it was huge, Quake 3 didn't have any yet it was huge, LoL/DotA doesn't have any yet are huge.
This is e-sports bro, we don't want expansions we want e-sports, we want tournaments all over the world with the best players/teams competing for juicy prizes.
