EMEA has a HUGE advantage of so many teams, scrim and play each other all the time in tournaments, that's how they get better.
Why not group these 3 countries? Isolate each one is a big disadvantage
Well... that's not how Riot's regional designation work. Even in League, each three countries are in their own regional circuit. We've now the opportunity to see all three in action with the East Asia LCQ on the horizon.
At the same time, I imagine that besides Korea and Japan being grouped up in APAC Franchising, China's potential as an independent market on their own means that they have the potential to be classified on a separate league.
