"It won't kill the scene, because the scene will die by old age lol. Assuming what you said is true ( future talents harder to come by), the scene will be stale, while other games offers something new everyday. Thus, slowly or quickly Valorant will lose their playerbase to competitors"
I still feel like it will be fresh since there will still be pretty but the same amount of new talent coming in and out of tier 1 with or without a tier 2 ecosystem. This is mainly just due to the older players retiring so obviously newer players will need to take their place. My point is more so that the skill of new tier 1 players wont be higher than if there was a tier 2 ecosystem
I agree with your last 2 points tho. I recon there will be like 3-4 orgs for each region that would pay full time salaries, especially bc of the new relegation rules. There will prob be 2 new teams each season for each region until 2028 or whatever where the org amount reaches the limit at 14-16 each region or however many it was. This is a decent incentive for orgs to invest as if they get a 30%-40% chance for ascending with a salaried roster then I would imagine a fair few orgs would take this opportunity.
