so. as it is now, for this example (Leather working), a level 70 character will use this skill only to level it to 70 (grind). The in-between skills will only be used once or twice until the next level skill and never again as they are obsolete for the cause (to use the top and only those skills). All the items created are to be sold to the vendors below cost.
Who will buy this items. Only vendors…

Ok. Now how is this good for the economy?
