[@RomanAria] We're looking for enough characters to cover each specialty twice, and as long as you choose a second which is different from Patch's Athletics then it shouldn't be too much of a problem.

Conversationalist, Pistols or Gadgetry would all be interesting second options for a medic, depending on exactly what kind of person you'd like to be playing as. Toughness would make sure you survived long enough to patch up your own wounds, and any of the other combat skills would make you into a very useful fire team partner.
