This is certainly a post that deserves some cogitation.
Find some way to get CMs the power to remove icons (or limit them to range+planetype) after the no-joy, and mute all players anywhere but on one open channel (no PMs, no squad text), and strictly limit them to range when in the tower, and KOTH would be a lot more fun and challenging.
A slow radar dot update would still stop the wabbits from avoiding fights, but without the gameid icon, players would actualy have to make an effort to get a shot at the wabbit.
This is a pretty much official event for AH, so it really ought to have HTC's attention. It'd be an improvement very worthy of the effort, I think.
