I'm prime for upgrading lots of gear, but I never have any ascendent energy or shards. How can I get lots of this stuff? NOTE: Yesterday I played on the moon for a while until a public event came, then I got something like a mote of light or some other non-ascendent thing. Today I wasted an hour on the moon before a public event finally happened, and I was about 2 or 3 seconds late to get there. I destroyed an exotic gun, only to get one of those exotic upgrade things (not the ascendent materials). I destroyed a legendary piece of armour and only got hadronic essence (which was unusual). Where/how do I get ascendent materials?
