I’m not sure if anyone proposed this idea before or if its already in the HoT, because it should be quite obvious addition to the Arena. Some type of countdown decoration for the fight/race/game to start would be very cool. Even the simple Sylvari flower mortar shooting some kind of numbers/signs/colors.
Feel free to post cool suggestions for decorations, like one person suggested Reward Box Decoration (that might be able to store several slots for rewards .. maybe… ) during the stream. That was a great idea.
