Remember when Xur sold exotic shards? Make that a thing again because having to spend a total 13 coins to get a pice of armor You already got so you can turn it into a shard is not a fair trade. The shard is all a player wants and is less valuable then the piece of armor, only good for leveling up exotic gear and buying glass needles.
1) buy a heavy weapon telemetry
2) go to the exotic weapon kiosk
3) use the telemetry
4) buy back a heavy weapon and equip it
5) consume like 6 motes (or maybe it was 9)
6) destroy the heavy weapon
You now have 2 shards, 1 as profit
Repeat steps 4-6 as needed.
It's stupid that we have to rely on that, but it's a lot cheaper than spending strange coins
