I would suggest doing named over HA's....I've ran a ton of HA's leveling alts and barely gotten any of those scraps. Glad I got them all when it was current. My guildy is looking for a set of these too.
They still drop. Getting the ones you want , however is a real pain. I spent the better part of 3 weeks farming the zone just to get a plate set, while doing so I got 4 chain, 2 leather, 2 cloth before getting, just 6 plate, which I dont show my helm, is enough to appear to be wearing a full suit, however I dont get the /ach for the suit until I go back and get another plate for the helm slot. There is no reason or why to when they drop or which may drop, I would go 2 days with no drops of any type, then the 3rd day get 3 of mixed types,, you are totally at the mercy of the RNG on this one.
So far I got 2 plate and a cloth. Those 3 came very quickly when I did a couple missions and I thought that might be the way but it's since dried up and I got no more. If I get to Dec something at expac release Ill just give it up. Its possible I might be able to trade someone plate or cloth crafted ornament for chain, but I guess unlikely. On Bristlebane if anyone reading this is interested in a trade.
Gives my ranger something to look for when i do hunter there. weird on fv scraps are no trade but finished item is though.
Its the same on live regular servers as mentioned above. The scraps are no trade but the finished product is tradable. This is also true of the line of Ambiguous Remnant of Devotion armor. The remnant are no trade but the final product is tradable
Ive now found 3 cloth 3 plate. Could theoretically complete the set minus helm if I can find someone wanting to trade - Bristlebane.
