So I was doing the weekly Spark of Dreams quest on many of my characters, and I wanted to collect most Flightstones from looting treasures. Unfortunately after looting about 3-4 of them it took me a very long time to find another one and I ended up flying around the zone for a long time, barely being able to find any lootable.
This resulted in me returning to Zaralek Cavern, which in my opinion has at least twice the amount of lootable treasures. I think the Emerald Dream is a beautiful zone but it feels slightly more-rushed than Zaralek, and I hope this can be addressed.
