Browsing this I recalled several years ago being one of the last two in a KoTH round, and the hot stick of the day was yapping on channel 2 with color commentary, and laying money on the other guy. It pissed me off and broke my concentration on the fight. It was not against the rules back then.
"Dead guys" in the tower shouldn't be doing anything that affects those still flying. (eg. giving check 6's, ID'ing other players still up, giving damage or status reports, color commentary, play-by-play, cheerleading, PM harassing, ect.) That kind of stuff is either in your ear or in your face. Its not like being out on the playing field with all that stuff being just white noise from the stands. Anyone not a CM or in competition has no business influencing those who are.
