I've suggested this before, but it was never implemented or officially declined, so......
There's still confusion when reporting players during the second half of stopwatch games, with players being kicked from the wrong team by people who don't realise that you're supposed to report players as the colour they were in the first round. (and even those of us who know this still make this mistake sometimes) So I suggest that as an alternative, or even as a preferred method, that teams should be specified as "our pyro" or "their scout" rather than "red" or "blue".
Anyone who says "!rep there" should of course be electrocuted where they sit, or if this is not technically feasible, banned forever.
