I leveld from 12->17 in the 3 first dungeons today, and I've only been getting Blue weapons(and some accesories) from the bosses, I've upgraded my weapon 3 times today, but not a single blue armor piece except the one from the quest.
When TESO is released on consoles the players will be used to a far richer loot structure in Destiny, the loot structure i TESO dungeons is just horrible, as far as I can remeber it's weapons/accesories only until lvl 49, with Epics starting to drop from 35.
It's not just armor the normal dungeons need, it's intresting loot in general, like quests, super special items, all the stuff that some of the other popular mmorpgs offer.
I also used the Dungeon Finder for all the dungeon runs(10+) it works, but it's still full og bugs, like invisible players, people see 3 team members in team menu when there really is 4. These bugs really need to be fixed before console release, because these problems can only be resolved by chatting usually and the console players are probably not going to chat that much.
