b4nnyYou're among them.
Unbanning everything in the hope that valve will magically realise that competitive tf2 is the way of the future is not going to help matters. Having discussions about the fact that Valve has decided to let this game die rather than pull their socks up and compete with overwatch will not change the decision that Valve made.
The way I see the whitelist discussion is that everyone who still plays tf2 does so because they love the game a lot. Like, a lot. When you consider the potential opportunities and competition that is available in overwatch and compare it to this game which has always been a meme to the majority of people (most people are idiots to be fair), the weight of the actual enjoyment of the game must be the deciding factor for the people who continue to play it, cast it, write about it, volunteer for it and just generally contribute to the scene.
So you should cater the whitelist and the ruleset to those people, the ones who love the game, and do so in a way that will make their experience the best possible. For mine, this would involve banning the 10-20 weapons that are annoying as fuck and allowed on the current whitelist. Things like the loch n load, cow mangler, rescue ranger, etc. Other people might think differently.
But you should listen to those who continue to play the game as it is now, not those who want it to be a super popular esport with majors and high level tournaments every week, because most of the people who wanted that have gone to overwatch. I was one of those people, but valve has convinced me that it's never going to happen. Eventually they'll manage to convince everyone -- including you, b4nny.
