Honestly, whichever way you look at it the response from valve has been underwhelming.
I wouldn't have much of an issue with valve creating their own 6v6 competitive format- and ultimately no weapon bans would be a good goal (still not convinced about class limits) if valve balanced them properly.
However, ultimately- valve actually has to create a functioning mode that people want to play. We can give them huge amounts of feedback. The idea of "relinquishing control to allow them to set the ruleset" is all fine but they actually have to create a ruleset that they're happy with, that people want to play. In other words, if we want to move from being a "grassroots" game to one controlled and supported by valve, valve need to create something that can actually compete with current 6es.
I have extremely high doubts that they will ever do so when they released out of beta a matchmaking version that was incredibly easy to troll by leaving- had no actual skill ranking that put players in games of equal skill level, was rife with cheaters, locked basic commands that are standard in almost all games like zoom_sensitivity_ratio and mat_monitorgamma, and had a memory leak that caused players' fps to drop and eventually crashed the game. Some of these issues still aren't fixed.
Asking the players to abandon any current gamemodes or rulesets for ones that are pretty CLEARLY worse is ludicrous to ask until valve make something actually tangible materialise. Sure the players can test various things that valve try and give feedback- but the current approach feels like "you the community come up with everything; we say yes or no and then implement a bad version" as opposed to "we come up with something, we gauge response and listen to feedback, we tweak and implement it". In the meantime, I think a large portion of the playerbase is starting to lose patience.
