In response to Ommadawn, definitely hasrh haha, however I dont think it should be that much of an issue. If spectate is enable by the game master and is shown that its active, people have the choice to join the room or not. For example, if people really care about people telling them where they are in tdms or in duel rooms lol, they already have the choice to 1. To Disable spectate mode if they are the host of the room or 2. Dont enter the room knowing the option spectate is enabled .
