Didn't played more than a year. Used to run 6-lvl solo dungeons back then. No loot now (almost) in new euro server. There items drop now (if they do)?
Solo dungeons drop less loot on average due to them being safer than other types of content. They essentially have a lower priority when it comes to black market distribution so you'll see a lower quality/quantity, especially if you're running a lower tier dungeon.
