I have heard that V16 material nodes are the only harvesting nodes in Hews Bane (TG DLC) if you have 10/10 skill points invested in that particular crafting tree. Whereas Orsinium had a mixture of both V16 and V14 mats (favoring V14), with V16 gear requiring 100+ Mats to create an item, this created a large demand and a sellers market.
However with this new update i think it will shift to a buyers market due to them being easier to get. I know this is the PTS and everything is subject to change but i have quite a stockpile of these materials and was wondering anyone else going to start selling before launch in march?
