Nope your denial means absolutely nothing every single team that has exited the scene in past year or so has literally cited the same reason this closed system keeping them out of competing for substantial money, fame nd sponsorship.
Trophies isn't how you measure a 'Tier 1' team if something like that even exists , Prx was the best SEA team for majority of it that doesn't mean they were tier 1 nd rest of SEA was tier 2. Nd pacific couldn't even win a trophy pre-franchising that doesn't mean whole region became 'Tier 2' by your definition. There will always be good teams there will always be mid teams , there will always be nad ones but you have to let that happen organically instead of creating compartments is what I meant.
