Patch arrived early and screwed me out of a bunch of free dust (I wanted to get a golden Murkeye with the quest and then maybe disenchant it)
Is that EU only? My Hearthstone still gas the old versions of cards, no Standard, no WotG.
It was a preparation patch. It doesn't add WotOG or Standard, but was simply a preparation patch which happened to disable the Murkeye/Parrot quest. My client has updated on my phone this morning. Maybe EU got it earlier.
I haven't checked how much dust I'll get for disenchanting Golden cards. I know I'll get something like 1100 dust just for disenchanting duplicates from the classic set. Not too impressive I guess unless I happen to have a Golden version of a nerfed card somewhere.
Edit: So I got 2700 Dust from disenchanting nerfed cards, keeping one BGH. I can imagine myself recrafting Knife Juggler if I don't get it soon in packs or something, so the effective dust is a bit less than that. I think I disenchanted at least one Arcane Golem awhile back for some reason and didn't have any left to get full value disenchant dust. I got an extra 500 dust from disenchanting the remaining duplicates.
