To be clear, I do think the XIV's "Dungeons" are too far gone into being synonymous with Hallway Sprint Simulator to make it worth bringing sidepaths back into them in any meaningful way (and care far more about seeing interesting environmental mechanics than multi-pathing or exploreables for their own sake), but I would love to see dungeon assets reused into a new content type that would be far more open to exploration -- call them, idk, "Delves" or whatnot.
