Around 90% of the mage epic 1.0 is droppable on FV. I didn't check the final 4 elements (what you end up turning in for the epic), but I think those were all no trade. It's the majority of the pieces used to get those 4 that can be traded on our server. Of the bard I'd say (without checking) that ~50% is droppable, though I could be off on that considering how long it's been since I've done that epic.
