Had this been done with something like dota or league there's a chance that it could succeed, but for a game that's just approaching one year old what's trying to be pushed is far too soon for the game. Plus the VERY high entry barrier for eSports orgs is going to turn a lot away without a doubt. The concept behind it is really cool, and I understand that blizzard doesn't want this to end up being a big failure, but for what is being promised there doesn't seem to be enough investors/investments into the game to make everything happen.
I understand there's not much of a way to get the top players who play the game onto pro teams and they're trying to solve that but as a player you can make a lot more money off of streaming and things like social media (ex: Seagull stepping down from NRG to stream more).
Also there are basically no LANs happening currently (with the obvious exception being APEX in Korea), so teams that are forming with players playing on international ping are more or less doing it out of love for the game, and let's not even talk about the different timezones and the hassle that it can be to get a visa to come to the US. Maybe if OWL was pushed off for a few years and the pro scene was built up further there'd be a better likelihood of success imo.
