ehm, you didnt really get the whole picture....
there are lot of hides on market at price that mybe is and mybe isnt low, but nobody is buying them, in first place i think on tier 3 hides, you can sell 50 of them almoust 4 free, becouse everyone is fighting monsters and getting hides...
my suggestion is, that when u make armors you need more hides/leather, that way people will be forced to buy, or to earn hides with fighting
torso armors should also cost more, cuz in the reall life and past, torso armor was the most important
