definitely this. If you're lazy for refining, just imagine for weaving.
Weaving is like 3x harder than refining to rank
and imo, it's a waste of brionac dur to use it on refining. Mainly with huge lucky on metalurgy
Weaving is 10x harder than Refine, and it's still very easy in comparison to other skills he'd have to rank eventually... which is why it's good for everyone to grind through Refine in its entirety, it and windmill grind are only basic preparation for the much worse things that are to come.
