Storm Weaver?

[Tigergeezer]

Does anyone have any experience of using Storm Weaver (looks like it's the energy version of the Backbreaker axe)?  I've just realised I have it in my inventory on the alt - I have no idea when I got it, but I'm not going to argue.   Is it worth my while maxing it , and what sort of build would it work best in (I'm guessing a hugger)?

I think the double UPC build uses it, pairs well with brightroar

Make heat hugger but energy
