Gobball Dungeon last room suggestion

This is less of a suggestion and more of a Dev requirement.  I know this is possible and can be done, but the Royal Gobball fight should spawn in multiple times at once in the last room.  

People are getting stuck in the last room of the dungeon in Mono VII for an extended amount of time.
Some players that start the fight will lock it and keep others from joining and let the timer run out instead of hitting ready causing the wait to be even longer.  
There are hundreds of players in the last room at once.
