Yeah I think it is a fundamental issue that riot wants to stay away from 'selling slots', while I can see why its advantageous I think the downsides are too great. The main issue in LoL is that the orgs hold too much power over riot, but in valorant 10/12 teams are dependant on riot, so I think if it's only 2 slots per region it's actually possible to give some leverage, as it means the t2 scene becomes more competitive
If we can have tier 1 orgs sustain academy teams, it might actually be better for the scene for there to be less orgs in t2 (many reasons like stability, guaranteed investment, less org owners waking up randomly and deciding that they dont want to do esports anymore). This would mean the entry point for some orgs becomes after ascension, instead of at the start of the season which mitigates the risk of not qualifying, meaning that perhaps orgs which wouldn't field a tier 2 team would actually end up investing in valorant.
I think we're pretty far from seeing GC players in tier 1, tier 2 I can see soon but until we see GC players in ascension I think it's not a conversation to have yet
