I really wanna see more things like this Tixinha tournament, where split 3 of tier 2 qualifies directly into a mixed tier 1/2 tournament.
Riot should make it an official offseason event that they themselves run (like Spotlight), so you can have one in every major region (I'd think something like: South America, North America, EMEA, APAC North, SEA and CN but maybe other divisions would make more sense)
From my understanding it's currently a streamer who's running and funding this, but the idea is so cool, and it actually gives Split 3 a real purpose
