Guild Wars 2

Looking at the BLTP, I am amazed Superior Rune of the Undead is listed at 84 copper. Krait is not much better at 88 copper. Under 3 silver are Afflicted, Vampirism, Grenth, Sunless, Necromancer, and Lich. Only limited availability runes like Mad King and expensive to produce Torment command good prices.

Draw your own conclusions from that. I know you can.

Something will have to be done, eventually, to help move these low-value runes.

They are cheap because they drop like candy.

Where the hell do you get your candy?

Every rune’s price is determined by how much they cost to be crafted.
For those that can’t be crafted but just salvaged or mystic-toileted: depends on demand.
Divinity runes where the most valuable for a long time until the rune rework that made Travellers what they are today. After the April patch Strength runes were in high demand for pretty much everyone who’s running a power build.
And before the last patch runes of Scavenging were ~5s, now they are close to 3g because they’ve been made part of a collection achievement.

Obviously you’re hinting at “condi necros are weak…” and that’s why most condition based runes are cheap, but that’s just not the case.
Also, sigil of bursting: 15g.

If you want an expensive condi rune, look no further than perplexity.
