Americas = Premier League
A lot of good teams that can all beat each other and some world class teams that could win international trophies.
EMEA = La Liga
A lot of good teams but a bit less depth than the Americas league but with the actual best teams in the world like Fnatic (Real Madrid).
Apac = Bundesliga
Paper Rex is Bayern and basically the only team that matters and that can win international trophies while Drx is Dortmund the eternal chokers.
China = Ligue 1
EDG = PSG a team with world class players but will probably never win an international trophy and the rest of the teams are kinda meh but can pull upsets here and there.
