Suggestion: Private lobbies for Mushrooms when using Bullhorn

Title^

The mushrooms stay open for anyone to join but if using a Bullhorn, it automatically creates a private room. That way, everyone gets a chance to get Elemental, Event, Large/Normal/Small rewards without missing out if 1 group takes it down beforehand.

If not using a Bullhorn, the lobby stays open to the public so all 4 spaces can be filled by random players that are not using a Bullhorn.

Mushrooms can reset every 4hrs or something instead of the 24hr rotations to keep the map fresh and interesting.

Mushroom Spaces, Bullhorns, and 3/3 turns would stay the same.

Tickets can still be used to enter mushroom either public or private.

Would REALLY like to see this implemented.
