I'd probably be a warlord. My personality is uncomfortably similar to Parson's, though I tend to be better at the big-picture production and resource management side of things than the small-scale tactical combat stuff. Warlords don't do that, do they? I guess that's an Overlord's job, but choosing that seems a bit presumptuous.
Otherwise, I guess I'd be a Thinkamancer (I believe learning and gaining knowledge is vastly beneficial and is worthwhile even for its own sake), Foolamancer (Hiding, disguising, and general trickery amuses me), or some other -mancer that specializes in disabling enemies rather than killing them. That seems to be my strategy in every tactical RPG I ever play; I either pile on so many status ailments that they're lucky if they even remember who they are, or if it's something mech-themed like Front Mission I just snipe everyone's arms off so they can't hold weapons anymore.
