Gunslinger and Sniper are mirrors.
Scoundrel and Operative are mirrors.
Hes facepalming, I assume, because you choose one base class of one faction and one of another, rather than saying *Sniper or Ops* or *Scoundrel or Gunslinger*
Either way it would be more accurate to ask the OP what spec of smuggler he's having issues with. Gunslinger, Scrapper/DF and Sawbones are all very different.
From his rage I going with scrapper, which as a BH with a KB and shield he really should'ent have too many issues with unless everything he has is on CD.
Powertechs use shields, not mercs. as I said, I am a healer, which is the bodyguard tree in the mercenary advanced class.
