seperated spectator chat

Hi, maybe a chat for spectators should be invented. So players don't get distracted by spamm and specs can still talk and even whisper to ingame players they know. I don't want censorship, so maybe it should be able to turn this special chat on / off in the settings for each game? Would be very useful for players in 2on2 so they still get what their teammate says (send rays! Why didn't you send em? You didn't follow the chat? awww f!@& off!!)
