I gave T'rahnu her prodigal combat skills because I'm fascinated by the idea of the lone travelling warrior who shows up, beats up the bad guys, and then leaves as quietly as she came, with few even knowing of her existence. I also like the dichotomy between someone who possesses great power but also is not terribly inclined to use it, as well as how someone with that kind of power deals with the expectations that come along with it.
That, and I just like the visual of someone who can switch between all kinds of weapons on a whim and still remain a threat. That's just fun, you know? And of course, as a fan of completely, overwhelmingly over-the-top action sequences, the idea of not being able to participate in that kind of thing (in a Final Fantasy game, at that) is pretty much anathema to my predilections.
So pretty straightforward, all in all.
