There are plenty of ways to get drops from monsters. In the Trammel dungeons, not sure if its activated, but you can get virtue armor weapons and deco from killing mobs. In Tokuno, you can get minor artifacts from fighting mobs, but its based off your luck and then you can turn in 10 of the minors to get a major. Ilsh, you can get artifacts by fighting and killing mobs that are paragons, but paragon mobs are tougher then non paragons. If you do gauntlet, which is located in Doom. You can get artifacts in there by fighting the mini bosses and the main boss, there have been many trips to Guantlet so I'm sure you could tag along.
Not sure if this is what you are looking for but is some suggestions for you.
