I agree the sport comparison isn't great but we should be aiming to get their as a community. No sport really started as a massive community with decades of rivalries and culture but with enough sport it gets there, riot should be aiming to fast track that growth because damm have you seen the income of American sport leagues.
My thought is more that if tier 2 can at least be close to a job in terms on income more people can try and pursue it and more orgs can try and pursue it. Riot isn't going to run out of money but the org's will, they need more support.
