When a gaming company gets into the MOBA space, they will inevitably try to grow an eSports community around it. The perception from the developers has always seemed to be that there needs to be a competitive to get interest from gamers. After all, League of Legends is massive and its World Championship has viewership that many sports leagues would be envious of.
While Blizzard has been trying to grow a competitive scene for their MOBA, Heroes of the Storm, since the game was in invitation-only beta, they are making their biggest eSports push ever for Heroes of the Storm in 2016. They announced their Heroes of the Storm Global Championship Circuit which will feature a cumulative prize pool of over $4 million for the year.
