Suggestion: raise their level/HP/AP and skill level to middle game stage. NOT their equipment or it would be holes for metagamer to exploit. Reason: Their levels and equipments are suitable for early game stage, but NOT for their role in overall storymap. Think: They serve as a middling man, selling slaves to VC for raw chemicals, and selling both chems and slaves to New Reno for... what? maybe Jet. They have unknown tie with Enclave. Combined this and we can suspect they are a branch of Salvatore but not Mordino (since the amount of Jet in The Den is too low and Mordino doesnt seem to know about Enclave)... BTW, I suspect Rebeca Dyer is possibly a Wright bride, and this is their effort to expand outside. Also, killing them and the NCR Ranger know, meaning they are quite famous in certain circles. Currently, Metzger and his guards are suitable for early level stage. A party of Sulik, Vic, and PC, armed with 4 dynamites, can cut them down with shotgun, .44 revolvers etc... Detail: Change their level to 16 to compensate for their 10mm pistols. That way their HP will raise so much you would need 10+ dynamites to do the job, which mean middle stage. Or at least shopping a lot in VC/Gecko (and/or NR/BH) Change their SMG skill to 120 I think. Because otherwise their AP ammo cant do the job. Keep their equipment as it is or metagamers would think of assasination one of them for easy highlevel loot.
