Switched to omni TS and feel like my DPS isn't high enough

Here is my POB: https://pobb.in/RfN3OcTn1RN-

To refer to - I've mostly copied Kobe Black Mamba - His POB is here : https://pobb.in/c_Go7k2xsZQB

Why is his DPS so much higher than mine? I understand his bow is better. BUt is there anything obviously wrong I've missed?

I think it's your bow, you have 1300+ omni anyhow.

You are missing 60% of your damage by not having the 60% conversion...the POB you are following converst the remainder of phys on the watchers eye.

You have 40% in passive tree and usually the other 60% is 25% gloves implicit and 35% gloves modifier.

Not having trinity is also a big dps loss. It's one of the best gems out there...

edit: yup you are gaining additional and not converting the physs you have. Go to calc on your POB and hover over the physical column under hit dps. If it's not 100% you are doing something very wrong.
