You are getting an implication from my statement that I did not intend to imply. It's true, esports have been around for a long time before and it is true, their streaming is not even that great even when compared to games in the same genre.

My argument is that the strength of their esports infrastructure is directly related to their F2P model. The game is accessible by all by being free, but also has a high ceiling of investment (both time and money). With that much capital, you get to see things like regular seasons of weekly competition that you can also watch live, finals in huge venues like madison square garden, pre/post-game analysis shows with a wide cast of hosts and personalities that all make a living off of the system.

TL;DR my argument is for supporting their F2P/cash shop model, and what can be done with it.
