Hi I was just checking this out and I find it really great. It doesn’t appear however that Windfury Weapon is an option for weapon enchants. I see Windfury Totem as a raid buff, but that is not the same as Windfury Weapon. On another note I noticed Sunder Armor and Faerie Fire as buffs, but not the Annihilator axe debuff which is similar, but stacks with the other two options.
In general we optimize for raiding, and debuffs from weapons tend to get pushed off targets quickly, so we don’t have an option for them specifically.
For enhance we assume you use windfury weapon when we do the optimization.
