Creating an economy for an entire MMO is pretty hard work. and adding new thing to it have to be thoroughly tested so they don't imbalance it further. I'm sure SE is working around the clock on how to make sure they can fix it. It wont be immediate, but changes will probably happen eventually. They Easiest fix would be if they can bump up the prices for selling high grade armor, weapons, and materials. Another good fix is to put Gil in treasure chests to split with the players. Humanoid mobs could drop pocket change aswell.
