LotRO ended up with loads of the bloody things. I never did work out why they couldn't just use money. (Yes, yes I know it was so that you were forced to grind a given dungeon a set number of times, but still).
No, only exception might be crafting materials for a expanded crafting system in the future.
One problem with the current crafting system is that its too easy to make items so they can not make the crafted sett as good as the high level looted ones.
If they demanded some rare items for crafting the sets they could introduce better crafted sets.
