Pirate problem

This is what I'm thinking, but if you want to have your maximum potential, like Death12341 said, it would be best to restart.

 Avoid/Accuracy build

Double Shot - 20
Somersault Kick - 11
Dash - 10
Flash Fist - 3
Bullet Time - 17

 Offensive build

Double Shot - 20
Somersault Kick - 20
Dash - 10
Flash Fist - 3
Bullet Time - 8

OR

Double Shot - 20
Somersault Kick - 20
Flash Fist - 3
Bullet Time - 18

I personally did, on my Pirates:

 Brawler

Flash Fist - 20
Somersault Kick - 20
Dash - 1 (I kinda regret this, should've been Double Shot...)
Bullet Time - 20

 Gunslinger

Double Shot - 20
Somersault Kick - 11
Dash - 10
Bullet Time - 20

Edit: Honestly in my opinion, Flash Fist is pretty damn useless for a Gunslinger. True, it's fast, but Somersault Kick is the way to go for mobbing if monsters get too close.
