Guild Wars 2

As an armorsmith, if you put 1 Bronze Ingot, 2 Molten Sliver, and 1 Vial of Weak Blood into discovery, you will get a Minor Rune of the Soldier (Master). If you put 1 Iron Ingot, 1 Molten Fragment, and 1 Vial of Thin Blood into discovery, you will get…the same exact thing, Minor Rune of the Soldier (Master).

Is this working as intended? Why would I use more expensive mats to produce the same product that I can make with cheaper mats? The same thing applies to Minor Rune of the Warrior, and probably other runes as well. Is this just an alternate way to craft the same thing? If so it seems like such a waste.

There still seems to be no way to complete this challenge…
