DoW/M/H/L Instanced Duty or Field Operation

OG Diadem didn't work out but I'd love something like RuneScape dungeoneering, just use the field operation system to make something

That or a deep dungeon but I realized the systems used for field operations might be a better fit

If you don't know what dungeoneering is, it's essentially deep dungeons but with crafting and gathering mixed with combat and puzzle solving

I think it would be fun to have minigames that encourage cooperation between DoW/M and DoH/L in one big open area
