PoE AsheBear_ builds

Here is a rough POB setup for frost bomb. A lot is missing and could be improved, but all things considered I don't think it is that bad... Gotta set up its defenses though if I want to use it. I am looking for general thoughts on it. I know it is missing a lot, I'm relatively new to making POBs so I still don't know where to add everything or how to make reasonable rares.

So I'm attempting to make something interesting with a charged dash raider. I have a very very rough pob setup that is not meant to look complete. A few questions I have: Would the Avatar of Slaughter route + getting more frenzy charges be better than taking Avatar of the Veil? I don't know how the POB deals with the exposure. I kind of like the Avatar of the Veil phasing route since it gives more defenses but at the same time the phasing may not be all that useful while using charged dash.
