Pivoting from an old Hexblast build

I've got a hexblast miner from TotA that I haven't touched since HBM got gutted and he's a total mess right now. I need to pivot to a new skill but I dunno what to do, PoB is intimidating and trying to pivot to Ice Nova only gives me like 4m DPS.

Does anyone know of any videos, posts, or other some such that I can use to update the build? I just want to mess around in Standard for the time being. I'll link the PoB directly too if anyone wants to look at it.
