The Reason why Gold is losing value compared to Gems is because Anet wants to inflate the markets with gold causing gems to skyrocket so players who don’t grind gold as much find it easier to just buy gems and get items from the BLTP or transfer it to gold I am sure that Anet will stabilize the markets in the next 2-4 months but for now I would just farm champs get 300+ gold and be happy with the changes there not going to make gold completely worthless its there main currency other than the random items they add every living story.
