Please keep in mind that this is ONLY a suggestion. What would you fellow players think of ZoS adding a feature in all dungeons and trials where you acquire a type of currency (or points, whatever) that you could eventually use to choose the specific item you're needing from whichever dungeon it is you're grinding? I'm not suggesting this should be fast, but it seems it'd be nice if you could work toward the option of choosing which item or items you want.
They already thought about it and went with transmute crystals which imo is way better.
I dunno, man. It gets awfully old running a dungeon over and over and over, ad nauseum, until you finally get, say, the rings or necklace (or whatever) you want.
