According to the EMEA League format explainer at 1:49
https://www.youtube.com/watch?v=vda9g4SRGdA
if EMEA Wins masters there'll be an extra spot in LCQ, effectively 2 teams from LCQ goes to champions
This should meant that the winning region in Tokyo will have 2 teams going to LCQ (just that EMEA the only region to explicitly say it)
By that meant CHAMPIONS Spots are possibly
Top 3 PAC League
Top 3 AM League
Top 3 out of 4 EU Teams at Masters (because there's 4 EU teams to Tokyo)
PAC LCQ
AM LCQ
EU LCQ
2nd LCQ of Tokyo Winning Region
(3x China as a 2x League + LCQ? << Given the by the time LCQ happened the Chinese server would be launched)
(I want to manifest "Host Region/Hometown Hero" spot, but Riot never did that)
