tier2++ scene is dead, tier1 teams don't care about other tournaments if it does not benefit them to be invited in TI. Most dota 2 pros are already begging valve to split the TI money to have a healthier scene for majors and minors. But valve does not care, as long as they can let 3rd party orgs like ESL, BTS, etc. to do the work for them.
If you still think valve is doing better than riot, just look at tournaments. LOL and Valorant have 0 betting site sponsor while CSGO and Dota2 is filled with scammy betting site sponsors.
