It sounds like you're really just looking for an increase to the loot drops in dungeons. This isn't an ARPG like the Diablo series where the entire reason for the crazy amount of loot drops is that they're very random in nature with most items amounting to nothing more than trash to the player. In addition, we get tomestones for completing content that allow us to purchase gear of our choice on top of the random boss and chests drops the dungeons have.
I don't see SE ever changing the loot system in standard dungeons to provide what you're asking for. If you're after the dopamine rush that comes from lots of treasure dropping, treasure maps would be the way to go.
