Guild Wars 2

Mental Paradox.3845:

I have never visited my home instance since I finished the story. Why should I? There’s nothing there, right?

There’s a few Home Instance upgrades you can get (from the past Living Story, and also from Laurel Vendors if you missed them), such as mining nodes, trees, skill points, etc.

Never bought one, ever. Have stacks and stacks in the bank. I use them to level new toons, if I didn’t instant-80 them from tomes, etc

If you think about what the Mystic Forge was intended for, it does exactly it’s job. It exists to remove gluts of low-level resources from the game permanently, with the enticement of MAYBE getting something good. (It also has a secondary use of being outside the crafting system for specific recipes)

Sigils and Runes:
With that in mind, what you proposed wouldn’t work at all. Suddenly, low-level gear with desired end-path runes and sigils skyrocket in price (minor sigil of force level 20 gear goes from 10 silver where it is now to 20-30, who knows how high, minor rune of strength, etc). You would NEVER craft Superior Scholars runes if your method existed, until the gear that dropped them reached such a high price that salvaging them wasn’t worth it.

Dyes:
The dye recipe exists. It uses Rare Unidentified (Spectrum) Kits. Four of those = Unidentified Dye. It is expensive, but that’s the point of the Mystic Forge.

Ascended:
4 Rings should be Random Ring, with 20% chance of being Infused
4 Infused Rings should be Random Infused Ring

4 of the same Ring Infusing is meh. That’s 40 dailies. If you don’t have the mists, vials, etc to Infuse the ring yourself after 40 dailies, you just got hosed. Badly.

Lodestones:
No. It doesn’t make sense. You can already upgrade cores to lodestones anyway. Cores too expensive? Upgrade Shards into Cores (this is actually sometimes profitable for Charged Cores!)
