The issues with channel 200 are derived for a small number of players. Squelch those and 200 becomes a great place to meet players on the other teams. Many friendship are made over 200 through the years.
Part of training, teach the newbies how to squelch.
I also think there should be a bigger presence of MODs in the arena with a bigger stick. Too often the political crap goes on too long before someone steps in. If a MOD is there to mute people right off sooner or later they will start to get the message that it will not be tolerated. The same goes for the bullying. It's pretty easy to see it happening when it does. If a MOD is on the ball and mutes them right off those getting bullied don't log off and/or rage quit. I don't know how many MODs there are but I don't think there are enough. I can see some friendly banter going back and forth, but some of the stuff you see these days goes way over board.
I know HTC want to "let the people play", but there have to be some limits or your just letting it all turn into a cess pool.
