I still believe that Valve would give a shit about competitive TF if they would ever release TF3 with matchmaking for both 6v6 for actual players and HL for the pubbers and at the start without any unlocks and actually add weapons that are balanced to both gamemodes equally as well for the pubs too.
If that won't happen, then Valve's competitive TF2 should also be completely without unlocks, but if that won't happen either then it's a lost cause, nobody should bother to attempt to save TF2 anymore after that.
However I guess we've already went beyond that point so I'm not sure what's even left anymore, I'm still just playing this game for fun with friends, and not to become a successful eSports gamer. If I would want to attempt with the latter then I'll just move on to another game.
