By the way, it turns out that Law and Order combo works hilariously with a melee Zer0 (duh). Remember that skill that gives you up to %20 health on kill, at max'd skill? I had thought that it was a good choice. But, this combo returns health equal to base damage on each melee hit. Not to mention an awesome roid damage bonus. Oh, also couple it with that skill that gives you an awesome movement bonus on kill.
Suffice it to say, when everyone else is playing a FPS, you end up playing Jedi Knight.
