Just grind a bit in Orr or Silverwastes get 20 gold or so from loot so and buy your way through a new crafting skill following a wiki page. That’s all you really can do. The Trading Post is much improved and the UI is better, but I still wish you could buy crafting materials via Black Lion from the workbench and plow through crafting trees faster. Then again, once you’re 500, you never have to do it again.
