Spectator camera may take a while to produce, we know, but in the interim can we at the very least have the chat panel while we're in that screen? That'll at least give us something to do while we're waiting for ~5 minutes, or however long it is.
I know this has the potential to be abused.. but as above it's not much different than guys in TS or Discord, with the bonus of keeping people in the game and engaged with their team while they hang out waiting for the end of the round.
