Should there be an option with XUR or the Vanguard/Crucible vendors where you can exchange energies to shards? Like to keep players from over using it, it should be trade 2 ascendant E/S for 1 ascendant E/S. Or should it just be trade 1 for 1. They should make this an option because I have over 100 energies and I barely have shards. And with doing the raid for gear and weapons, I always end up getting more energy than shards.
