Paper reviews needed for NIW?

Hello,
Do you think it will help to include paper reviews for my NIW case? I know it is a must for EB1A, but what about NIW?
I have 12 reviews btw.
I am from China.

to Roger:

It helps, but it's not required. I didn't have any paper reviewed but my NIW I140 got approved

to Roger:

You're from China and you're applying NIW? Isn't the wait super long right now? If your creds are too weak for EB1 I guess there's no choice but wouldn't it be better doing EB1?
