So, I need one item (wrist) to complete a pvp transmog set, and I see that it’s available from the Echoes of Battle vendor in old Dalaran. But, I haven’t been able to find gear that I can obliterate. The only other option is to buy the complete set from that season’s vendor (they only sell full sets, not individual pieces (how dumb is that)), but I don’t want to spend 12 marks of honor for just one item. I’ve searched forums, asked others in game, and not one single bit of info exists. I can’t believe it. So frustrating. Can someone please help?
Pretty sure the only gear that could be obliterated for that was the current season pvp stuff…which I seriously doubt is available anymore. You’re probably stuck buying the entire ensemble if you really need to complete the set.
Unfortunately, this is your only option. 
That’s just unnecessarily retarded. Why would Blizzard do such a thing?
Thanks for the responses.
Sephtis, you actually do have another option. You can collect Veiled Argunite on Argus, use it to buy armor tokens from Thaumaturge Vashreen. I believe there’s RNG to what those tokens create, and a slim chance of getting the piece you actually want directly. But moreover, those pieces ARE Obliterateable for Echoes of Battle. This is not a fast way to get that piece, but it’s an option.
