Last season was probably the best we've had in quite a while. It was a very competitive league overall, with many strong players returning to the scene. It'll be interesting to see how future leagues shape up, especially since a number of players have stepped away from the scene + Elite grand finals cheating incident.
Now, regarding the "no foreigners" rule in RGL... It really doesn’t make much sense. The South American scene is mainly centered around three countries: Brazil, Argentina, and Chile. No other country has managed to win Elite (the highest division), mainly due to ping issues. When you exclude those three countries, the rest typically get similar or even higher ping to Brazil (where all matches are played) compared to North America. For example, Peruvians average around 100 ping to both Brazil and NA, while Colombians actually get lower ping to NA than to Brazil. So it’s unreasonable to classify those players as "foreigners" in RGL when they experience lower latency in NA than in SA. Uruguay and Paraguay also have low ping in brazil but its rare to see players from there.
