- The ability to do a long rest while in a dungeon, where your party just somehow magically appears in the camp seems gimmicky at best.
While I agree with you whole heartedly many people would be vehemently against this. It would not be hard to toggle resting on/off in dungeons from a settings menu which may be a solution that pleases both sides.
What about this as a compromise:
On the overland map, using Long Rest sends you back to camp.
In a dungeon/the underdark/etc, Long Rest is grayed out; but if you clear out a large area, killing all hostiles, it will become unlocked. Using it here puts a campfire in the middle of a room and your current party of 4 sleeps around it. There's a chance for an ambush based on what monsters live in this dungeon when you awaken.
