Please god no.I wish there would be a extra bar, lets name it "Focus"The bar loads during a week and if full you can craft a Q6 Item (if your perks allow it)
Wold be in my opinion the best way to reduce the overpowered crafting
Q5 would be allways possible (if perk is taken)
+a 2% Chance that a item loose a quality level on repair
No more abitrary gates on crafting, it is not over powered, if anything its the exact oposite and massivly under powered as it stands.
