They want to make these items slightly harder to make.
They want to use currently existing in-game items to accomplish this.
The current requirements are opposed by a large majority of the people who are aware of these changes.
So.. just a quick thought.
Rather than Dragon Scales, or Giant Slayer Knife, Flawless Sib Shards, Blood of Dragons, etc. unrealistic stuff...
Gianthold Relics. Draconic, Elven, and Giant Relics. Drop out of Rare chests, and every quest out there but Tor. (Reaver's Fate is a Raid, not a Quest.)
Perfect idea to implement them. It limits crafting without overlimiting it. 3 Each for Regular Bane, 5 each for Greater Bane.
