Just a thought, would it be nice to have a way to purchase upgrade materials at the tower? Remove the glimmer cap and add a vendor to the tower that allows you to purchase materials. Maybe not the legendary items, but at the least the farming materials from each of the planets. Having maxed out glimmer is pretty pointless, and there are only so many things you can buy. I think being able to exchange for other items would give glimmer more of a purpose.
