RAT Bow build

Mainly just looking for advice at this point. I know the build is far from perfect, but it has plenty of life and damage, although the totems aren't really focused.



Ranged Attack Totems, bow. Probably running Ice Shot or Lightning Arrow.
I wanted to run Iron Grip so that I can add in to more STR nodes and such without feeling guilty, but I'm not sure if it was a good call.

I left a lot of freedom on board for play-as-you-go, meaning there aren't really specific item or skill gem goals. Supposed to be a hardcore build, taking any/all suggestions/advice.
