Figured I'd give it a go - I really enjoyed playing with the rifle and being very gung ho, so I built a rifle-based build that drops turrets in the back for support. It's very defensive, because I tend to get right up in the enemy's face a lot with the double jump shot doing damage on liftoff and landing.
