That four Pitt slaver lackeys with lead pipes can beat you unconsciousness regardless of your melee combat proficiency (or, in the case of that which prompted this request, my having been encased in T45-d power armor at the time) is...well, quite frankly, it smacks of Bethesda's usual penchant for blatant railroading. I can't be the only person of this opinion.
Is someone up to the task of creating an alternate disguise-less entry to the Pitt that would allow you to overwhelm the Pitt slaver regime by force WITHOUT being overwhelmed and disarmed first yourself? Ergo, one that would let you march in, guns blazing, and wipe the floor with the slavers instead of being taken captive the moment you set foot in the place?
I realize that the mugging scene is part of the story, but it is a silly and unessential part, in my opinion. Anyone who has discussed power armors in the PANZER thread can attest to the superiority offered by a suit of power armor. Whatever the method for bypassing the mugging part of the quest, that is the basis of my argument: Armament and combat skill should determine whether or not you can be overwhelmed by the Pitt Raiders.
