Simple, just list your top 5 wishlist cities. Here are my 5.
1.) Seattle, WA - This city in particular is one of the major cities of e-sports gaming and is very popular. It is also one of the biggest cities of e-sports outside of California so other than just 3 CA teams for the far West, maybe Seattle could be a good spot? I think FaZe Clan is reasonable for having that spot if it were to happen, but I have a feeling that 2nd LA spot was made for FaZe itself.
2.) Colonge, Germany - Outside the US, Colonge is no doubt one of the biggest EU e-sports cities, also OW is in dire need of another EU team. Investing in this city for a spot is a great idea, after all it is one of the largest platforms of e-sports in general, meaning there is an audience. I would say any EU team could actually buy the spot itself if they have the money. Possibly a return to Fnatic? Maybe.
3.) Singapore - I like the idea of Singapore because this is where the best of SE Asians teams/players can shine, Singapore is also a tech based city so the potential is there for an investment. I don't see a problem with this because SE Asia is actually on the rise when it comes to OW e-sports.
4.) Sydney - I also don't see a problem with this city or country except for one thing, travelling other than that it is fine. I'm surprised no one has invested in a team in AUS because there is a scene in there for sure. The teams that could be bought from an organization could mostly likely be Blank Esports, a maybe would be Flash Wolves, and a least likely would be Ardeont.
5.) Some city in Brasil - Brazil has a large significant e-sports scene, only if SA expanded into NA minor or major tournaments in OW, I can assure you that they can pick up on some ideas on how to become a challenger. However, there are people willing to see this, but funds might not be enough for an e-sports multi million corporation for OWL, I don't see it just the way OWL is working. If it were to happen, I would say Brasil Gaming House or KARMA (aka Team Argentina) could settle for a team.
Bonus:
Tokyo, Japan - My only dream is to see Japan as a spot for OWL, I want to see Japan as a competitor for SK and China. I feel like the only problem is that, there isn't really a lot of support of OW in Japan itself. Possibly Team Japan and JCG Master (Japanese Tournaments I believe happens at least 2 events a month? Not sure about that tbh) could spark a new scene of e-Sports in the country?
