Worse is the melee. Best Warrior build? Rifle. Go sniper, or you WILL die like a dog in the street. Doesn't matter if you strafe, most hammer attacks have a half to full second wind up, and the Greatsword damage dealer roots you, not the enemy. The skill is One Hundred Blades.
Armour has no effect, other than some stats, I tested this for three straight hours of swapping between going commando and full suit for six levels of heart rending pain.
