In game quality effect durability right? so, how is iron would have better durability then steel?
Skill would be needed to craft out of that iron or steel etc... with low skill you won't be able to craft higher level anything by using higher level resources, but you will give ability to low level players to find higher level materials, and because they won't be able to craft anything yet due to low skills they would go out and trade those resources for what they need.
