Maybe you'll meet some guys and form team and grind some ESEA/FACEIT leagues but dunno
I don't know how the NA faceit situation looks like but if it is similar to the ESEA leagues condition where half of the teams are brazilian then it's really bad
In EU, if you're really really good, you could be scouted for a tier 3/4 team or an academy team and work your way from there. xertioN was picked up by mouz NXT when he was an FPL-C player.
In NA? No chance.
The fastest track to a good team in NA is to play open with other good players that are your friends. If you have good league stats you can get picked up by a good team or you can progress to a higher division with your current team. Nobody cares about pug rank in league.
