Are you serious? Excellent counter-resist and depr prof, that's already very good for the main use of a Willow. Even though overall its PXP is a bit low.
I know its not SDE, but would it still be worth something?
Maybe, but not more than 100-200kC. It can only ever be mildly interesting for someone who is still dragging his obsolete Mag force shield at Lvl325 and he's also sitting on a huge pile of soul fragments.
