An Idea to make economy better by choosing statuses at creation and then not being able to level them in game, and craft items with Q/D based on statuses.
For example:
Dexterity and Intelligence at 100 and also tool-craft skill at 100, then one could make best Q/D on tools.
But if Dexterity and Intelligence at 50? then one could only make tools with moderate Q/D even if he has tool-craft skill at 100.

And H/Q items should really have better bonuses then moderate quality (M/Q) items.
I am not sure if bonuses work at this point, I made all these gear but don't really see an impact out of them, that should make a difference, we really need to have a difference between high Q/D and moderate Q/D in order for people to buy those gear/items.
