I think its right on if you ask me. You have 3 DoL farming for 8 DoH. It seems logical that you cant expect every swing of your tool to yield exactly what you need for what your doing with your particular DoH. The way everyone else does it is sell the items your not using to by more of what someone else farmed that they don't need that you do, because they are farming for a different DoH. Its give and take. Its what drives the part of this games ecomony that is working.
