The CN scene has huge potential, will Riot be holding open Invivationals for them like this year ?
If so, that's a fat waste. Tier 1 Leagues always create a scrim bubble, outsiders can almost never compete.
China is big enough for their own market and league. There'a a reason why League has a separate franchised circuit there alone. Riot may have the social presence there and they somewhat took the gamble with having CN teams on the EA LCQ, but as far as integrating them into the larger VCT ecosystem — that's a different story.
Putting them with APAC will be a disservice.
Most can't speak English well sorry to break your bubble . Aside from basic rank calls communication in team environment is different. Also these "international signings" you speak of is only GE who also is currently forced to sign different talents because they don't have enough good Indian players. Wait 2-3 years and it'll be a full Indian roster. That's just how orgs and playerbases are in Asia
for EDG in specific Kang Kang as seen in Yinsu interview he speak very little english. I've seen Haodong speak basic english in foxz stream. Basic rank calls communication they should be able to... But when it comes to strategy meeting/discussion by coaches and team synergy good level of english understanding is needed.
