I would love to see that tool quality (QL) have a factor on the outcome of an item. It used to be this way.
Now only the bonus on the tool matters. IE if you making leather armor, you want to use Master Pioneer Tools because it gives +15 to leathercraft. However, using a 90QL tool vs using a 100QL tool will not change the outcome.

This used to be the case that high end tools would make a difference. I see no reason why it was changed, but I think one day it was broken in a patch and never fixed.
