This post isn't addressing the underlying problems, just the outcome of it. When NiP were on their 87 map streak, you think the solution was to tell get_right to leave the roster?
Any competitive game needs the young players to step up and keep the game moving, but as it stands currently, it's incredibly difficult for that to happen. When your option is literally waiting an entire day praying to get picked once or twice on PugChamp, how exactly are you supposed to improve? Not to mention that other platforms, such as FaceIt or essentials.tf, would much rather blame the community for idealistically "not caring about the game" instead of actually working to improve their shitty platforms (though essnetials.tf has started to do this). Factor in that these sites rarely have a backbone to ban toxic behavior, which is incredibly off-putting, and it's not a massive surprise to see the lack of development. It's not like players can't improve fast, look at someone like Goku who won IM in his third season, it's just that it currently is incredibly difficult because the service isn't there.
Even then, can you really blame those platforms and outlets for not providing good service? Where's the incentive for them to make their platform even half-way decent? Same for players. You think a team like MAL is playing IM instead of playing invite four seasons in a row because they're "lazy?" Get real. Why would they play invite where only a fraction of the season will be remotely competitive and their likely to get nothing out of playing it? And the reason why the skill gaps exist is because the pool of willing invite players is incredibly small; there is like four skill tiers within a nine team division, how is that funner than getting a free check and playing with your friends? That's a problem that can be solved with actual incentives and growth that goes beyond "omg you NEED to support the comp scene!"
My recommendation is that the community creates a system were young players can continually improve and enjoy the game, and there exists greater incentive to constantly practice the game (more / better tournaments, better services, more LANs, more benefits). And when people actually have hope that the TF2 scene might actually go somewhere and there's some motive behind that, maybe you'll eventually see some people actually trying and wanting to compete. Even now, look at the pool of players who still PUG and are around right now. You could easily make multiple playoff invite teams with them. The reason they aren't playing isn't because they hate the scene or whatever, it's because why would they play when there is hardly any motivation too? That shit isn't gonna happen overnight, but imo it's a much better solution than some idealistic B.S. about teams staying together and some temporary solution about dismantling the best team.
Sorry for the long triggered nerd essay, but god damn I hate this narrative that it's the players fault for all the woes of the community. It should really be a testament to how great the game is that people actually still play it considering that on paper, there should borderline be no reason for this game to be alive. You need to start from the foundation to fix the problem, not the head of it.
