These guys were designed a long time ago, when people were spending a lot more time in low-level quests...as a result, their prices are really high right now (50 of certain collectables) for a random augment, or Astral Shards to pick one.
With the improvement of augments - which I think has been a general success, aside from the bugs - the way we acquire augments seems like a useful thing to revisit too. Could we tweak the prices on these to make them more approachable, especially for newer players? And could we change the Astral Shard price to Remnants, which seems like a more appropriate tier of "premium currency" for these type of rewards?
