I think his comments are on-point, depending on your weapon.
I found Hammer Warrior exceptional in melee combat. There was a lot of control: Between Staggering Blow, Backbreaker, and Earth Shaker, I could keep a foe interrupted / stunned for quite a bit of time. Hammer Shock keeps them in melee range if they're trying to escape. If they get out of range, I can switch to Rifle until my jump in hammer skills are recharged.
I found my Ranger pretty strong with Axe / Dagger, which involved him rolling around and dodging a lot of stuff.
