I'd like to see an area that was impacted more heavily during the collapse. An area that incorporates a pve element, and yes pve. Raids and nightfalls are pvm (player vs. Monster) where as pve is player vs. Environment. Some thing like either a volcanic area that magma can hurt you, or a dying planet locked in some kind of super space storm that with debris and lightning. Also something like smoke from the erupting volcano and heavy rainfall to reduce vision.
