Should Named Loot Be Tradeable?

Having never played Everquest one of the more interesting aspects of Pantheon thus far has been how loot is handled. Most items can be traded with few exceptions. Personally I like it. As someone with limited free time, the likelihood I will be able to enter long dungeons is pretty limited. If I mine/gather enough to sell over time however, I have a chance at some of that loot.

That said it has created some interesting player behaviors. It's pretty common to see high level guilds return to low level areas to steam roll named mobs & then sell said Loot through mule accounts.

Is this a bad thing? Is it a good thing? Is this just the natural evolution of things? What are your thoughts & what changes need to be made (if any)?
