It cost fuel to make shards then you have to deconstruct and pay fuel again. I think that is okay but it costs too much shards dust now. I think the latest update made it insanely too expensive given tier 5 shards have a lot of trouble catching tier 4s.
It’ll be very frustrating see rare illuvials on stage 3 runs escaping frequently. Both wasteful on energy, shards and overall just a very expensive waste of money and you have to limit how often people come out empty handed in these situations.
