Ludwig suggested doing a world cup near the end of the LxT 3 stream, and I personally think it'd be a great idea.
This year had an amazing format but I'd fw a world cup heavy. Even if they do this years format again it'll be great, best off season event in this game so far imo.
here's a few suggestions for countries (these are hypothetical, it doesn't have to be them)
USA
Canada
Brazil
UK
France
Turkey
Japan
Korea
That'll be 3 AMER, 3 EMEA and 2 APAC for example (APAC sort of gets the short end of the stick, but I think it'd have to be that way because of the timezones). I think inviting 8 teams from the biggest countries would be a good place to start, just to see if the idea sticks. 8 Is a nice number for a double elim bracket too so each country gets a minimum of two matches
