The 5 dur thing is really important to know though for crafting. It means that when you use Waste Not, you can use one Tricks of the Trade during it without losing either of the two extra steps that Waste Not gives, making Waste Not not a terrible skill. With Waste Not II, you can use a Steady Hand [II] in the middle of it without wasting any of the four extra steps that Waste Not II gives, but you can't use any Tricks of the Trade during it, making it cost far more than it seems. This essentially makes Waste Not II only useful in macros where you aren't going to use Tricks anyway.
