Typically, it's tough to make a lot of profit without farming your own nodes, since the raw material is used not only for making a finished product, but also for just grinding out the tier for proficiency. So you're competing with L85s with money to burn who need the material to just power through to Riddermark.
You might be able to make some consumables that would sell, but I don't know what. Champion Fervour potions or Hunter Focus potions are some things people may use a lot of and be willing to accept a slight downgrade from Riddermark. Probably not so much bow chants. But maybe Light and Fire Oils?
Really, I'm just surprised that there's a bigger profit to be made at *any* tier by making a product, compared to selling the raw materials. But I guess they have really increased the drop rate since I was a budding Scholar.
Work like no one is watching, dance like you don't need the money...
