Yeah, you can do a 9 PD longbowman that hits like it is shooting bricks out of a cannon.
I did it, wearing light gear I never got the message like Native is suggesting. I had 30 body armor and still had enough WPF lol.
He was probably trying to wear plate and have 9 PD, oh native.
It is sad that you can't have 10 PD by level 30 though.
