I was hoping the "Rising Pillars" would behave like (and give off as much light as) other outdoor lampposts (glade, riviera, oasis, etc) at night.

Instead, the crystal gives off no ambient lighting during the night hours, and with the limited slots available for placing items that issue makes it difficult to justify ever using them.

Were they an actual meaningful light source, I think they'd make a welcome additional option when choosing between lampposts.
