You cant craft the Dragon swords, thus they aren't devalued, they are still annoyingly rare 8 stars in 8 star hell, also disassembling them had a 0% chance of dragon remains until now, this makes your first arguement null.

This was more towards the item (swords) vs. material idea as of now (not then). You have somewhere between 20-30 resource nodes all near each other and that give you a 1-per for Dragon Remains, which replenishes over-time while the swords give 0-4 while, like you said, are not too common. While it may be a new material: it's not particularly hard to get (which is what I was trying to lead into).

As for Slydria's post, it seems like a decent base idea.
