Next Tier Dungeon?

I know a lot of us are just whooping all of these dungeons that we come across, without a whole lot of fuss or issue besides blue slaads.

What are thoughts on a new dungeon that would require atleast 5+ people (like everyone has to stand on seperate platforms to even enter). It would be neat to absolutely need the power and know how, with multiple classes needed to unlock certain areas, areas that need a lot of fire power/elements. I’ve heard there is some secret dungeons, so maybe this is already a thing.

Anyone want to make a conversation of this?
