Riot being the TO for this is good (frankly I don't think any other TO would make much sense anyway).
As for GC, they can probably have Champs done before October if they optimize the schedule. Depending on the region, kickoff is currently anywhere from January to March, stage 1 anywhere from February to May, stage 2 anywhere from May to August, and stage 3 from September to October, with random tournaments sprinkled here and there and everywhere, all leading up to Champs which lasts a grand total of 10 days. It's a problem and they need to fix it, even if they don't run a World Cup
Also you've had 3 different flags since we started this mini thread 😂
