as far as i know, the map "Final Rush Pro3 4v4" gives people rating when playing survival on that map, making it possible to farm rating on it.
making it unranked would be nice, thanks.
also (one of) the reason this has been undetected for so long is that the ranked/unranked indicator in the lobby has been removed.
i would suggest re adding it, but making it the "standard conditions" indicator instead (same function, different wording)
