Guild Wars 2

Will there be away to extract our runes from Ascended armor without destroying them?

(and with Legendary armor coming soon, this will be a concern too)

They didnt release any information that would suggest that this will be possible in the future without using the upgrade extractor from the gem store.

And considering binding runes and sigils upon slotting is their main sink, i dont think they plan to chance it without creating another sink for them first.

Overwriting runes is the primary sink for runes. Basically, for runes to retain any sort of value anet intends that they are more often destroyed than salvaged.

This is also why, barring some cash shop options, you’re usually faced with a choice between keeping gear, or keeping the upgrades in said gear.

From the stream they did in Twitchcon, they are figuring out some way to address your concern.
