Should have the other local leagues running along side to try & get in, even if Riot vetted only as well but only the main league gets the "rev share" & spots for Masters
Ex: Top6 NA (from Stage 1 2022)
The Guard/Optic/C9/XSET/LG/V1
Top 4 BR: (from Stage 1 2022)
Loud/NIP/Keyd/Furia
Top 4 Latam: (from Stage 1 2022)
KRU/Leviatan/Fusion/Lazer
and at the end of the stage or before the new one have a relegation playoffs between bottom 2 from each league & top 2 from regional
Ex:
LG & V1 in a promotion/relegations double elimination playoffs vs SEN & Knights
where only 2 spots per region have the possibility of changing
don't know how the invites for masters would work with the Americas league, but hopefully this means more competitive masters, even its less diverse
