Does anyone know if certain public events are more apt to give you ascendant energy over others? I've usually gotten ascendant shards from the devil walker event in the divide. I've only done the defend warsat event twice at the skywatch but I have gotten ascendant energy both times. Is that just a coincidence? I need about 6 weapons * 18 ascendant shards and I have about 20 ascendant shards.
