Dungeon rewards are really poor

On the second world difficulty level, the early dungeon bosses can be quite challenging. They certainly take a long time to kill. But the rewards from every dungeon boss so far has been a smattering of gold and 1 magic item. It’s really deflating to get such a paltry reward for completing a dungeon and its boss. I get that the unlocked aspect is the main reward, but there seriously needs to be a boost to the dungeon boss rewards. At least 2 epic items with a medium chance of a legendary.
