Iron Grip For Elemental Bow Ranger Or No?

I am having a huge problem trying to decide if i want to use Iron grip or not in my Lightning arrow bow build or not What is your guys opinion on Iron Grip? The build I am going to use has 60% increased Physical damage and i know iron grip does not count as a projectile I am just torn on if i should pick it up anyways since it increases the physical damage and i could use frenzy for single target I am just really torn and i want your guys opinion on Iron grip

I took it. It is very close to 30% weapon elemental damage, so I figured why not grab a little extra dps.

The thing is everyone who makes these elemental bow guide builds on the forums say it only increases the dmg of the "Physical" Part of the tool tip on your Skills but technically that is increasing your dps but the real question is, is it worth it to pick it up if im already picking up a shit ton of weapon elemental damage already to sub in some more Survivability Now thats my real problem trying to figure out if its truely worth picking it up if i want to be a good dps and surv

Anyone's opinion would help alot thanks! in advanced

more info on what i want to use for my abilties

Lightning arrow AOE
Single Target Either Frenzy / Burning arrow / elemental hit

Would Iron grip help me here is it worth it?

If u take it for 1 passive take it, but dont take 4 or 5 passive point just for iron grip
