I too have given this some thought lately, and have an idea. Just like in the game, we need to wing up when it comes to controlling useless and bothersome banter. What I mean is , when someone askes another person to stop talking up the channel, we should back them up.
It works a lot better when more than one person lets the talker know that the chatter is interupting the game for others. I know that from now on I'm gunna do that, cause it's just starting to get outta hand, and we gott nip it in the bud.
Just my 2c.
