I'd rather characters were unique rather than "does their job an order of magnitude better than another troop of the same type." I think Van Zant is actually a good example of a character who does something unique. Dart is just "A midfield infiltrator, but better, without a commensurate hike in points." McMurrough is "A warband, but better, far better than his points cost would indicate." And there are non-specialist Zhencha profiles, my man. In a mission like Firefight where you don't really need specialists, Dart just makes Zhencha look like shit. The fact that Zhencha die to Antipersonnel Mines, are hackable, and Dart is highly resistant to shock ammo and immune to hacking is a horrible joke.
