ngl, as much as I want orgs to return and invest in NA, at the same time I sort of dont. Mainly because orgs still notoriously overpay their players to the point of nearing bankruptcy like with Valorant-focused Sentinels who are spending hundreds of thousands on salaries alone while financially ruining themselves in the process, and are on life support as a result. It's basically one of the reasons why I've stopped caring about the NA scene.
If you want to give players a high salary fine, just make it that it's high enough to be livable but also financially wise. Not in undeserved amounts.
Also, I think you're underestimating Brazil's ability to try to get a grip. They've been recycling the same pros for who knows how long, despite having the talent. But they're literally refusing to give them a chance while also artificially inflating outrageously high buyouts. The only Brazilian team that even has any sort of potential future is MIBR.
And if we're ever going to bet on a non-EU region to be able to give us high quality CS and be able to contend against EU opposition in the future, Asia is ironically the way to go since they've now shown that they're capable of keeping up with EU opposition despite the disadvantages they have as a region currently.
