I love the requirement of using the attachments. It allows the PUP to be incredibly strong, but not overpowered because you have to que in each maneuver. With that being said, I run into very few mobs that I can't solo as PUP. Take the time to gear yourself and keep both your skills up [Automaton and yourself] and you'll have little problems.

Sure you're not going to get the raw damage output, but like Helyos says, does mnk have a bot running around casting Cure VI at your command.
