Well, there already is a cool down, and sometimes in clan wars one must use 3 separate radio commands in 5 seconds, so I don't think any further edits should occur. Sometimes players radio spam and there's really nothing that can be done to long-term improve PT. I would certainly appreciate a chat mute function. I currently put something over where chat would be in public games, and I can certainly assert that it greatly improves my gameplay. No negativity or being influenced by other players, just pure pawn tactics
