Fury dealing with PI

[:1]So, I'm level 74 just starting Hell mode and I respecced Fury at 70 after I traded for a Ribcracker and upped/shaeled it.

My question is dealing with physical immune monsters- should I have put points into rabies for them? My current skill build is

Lycanthropy 20

Werewolf 20

Fury 20

Grizzly 15 (or so) and rising

Misc. 1 each (prereqs, HotW)

I'd be fine with respeccing my grizzly over to Rabies if that was better, though I do appreciate him as a tank. I'd just heard that Rabies wasn't so good for PvM.|||This amulet should solve all your PI problems. With fury's zeal-like attack, you should be proc'ing amp dmg pretty often.
