Someone already mentioned that if they choose to go this route that the majority of players will just automatically skip over the spectating option due to the fact that it will get abused if they DON'T add a delay. Thus making it a pointless addition as it will most likely not be used much at all.
Also while we're on the topic of addition game room options...can we make it so you can edit those options as room master rather than choosing them before you create the room?...
