how many NA teams?
I wouldnt really take the 3 regions as an argument here. The factors are: playerbase, number of proteams, competitivnes and fanbase.
While NA has bigger fanbase, EMEA clearly has more players+teams. I agree EMEA should have more teams but I put the ceiling on 4/(5 if the win) because it seems uneccesary to have so many teams. Its better having more representation of other regions. If u have 6 EMEA u cant put them all in seperate groups (I mean riot did it with 4 anyways but they wont do it again). Masters are still global LAN events and we wanna see the different regions clash it out, not 6 EMEA teams playing against each other and potentially having like 4-8 games between the same region
