Right now, at most depths, there are maybe two or three possible levels. They're on a timer, and you can pick which of the levels you want if you wait for it.
I propose that instead of being able to wait for the levels to cycle through, the game should pick which one you get randomly. Encouraging players to stand there and do nothing for minutes at a time is bad game design. This would fix that problem.
Right now the random level mechanism is used only for graveyard/treasure vault.... I assume OOO intends those levels to be extra profitable, so they don't want everyone to always wait for them (though vault is not really that profitable currently).
Allow players to choose level is a valid strategy... e.g. you don't really want to mess with T3 wolvers with your chosen equippment. I don't think taking it away completely is the way to go.
I've seen suggestions in other threads that OOO could make it into another crown sink - pay crowns to make the gate shift right now. I think that is a good compromise. Pay, or wait. Party disagree about waiting? Go solo or kick.
