Desolator on weaver

To me this seems like a really nice item to get on weaver, since the armor reduction will work well with the double shot ability, yet i have never seen anybody get this. Why is this item not more popular on him?

Sincerly

• a gold scrub

EDIT: i see people saying its an orb effect and doesnt work with germinate, but im pretty sure its a debuff, and will work on both shots
