Although I haven't used her, I'm not quite sure Arashara deserves a B+, much less any B grade at all. She really doesn't seem like she can do enough to earn her points. If she were ranged, then I might change my tune, but as is all you can do with her turn is chance a Shifting Sands roll and a melee attack of 4. Her being pretty frail also means that using her attack might be an effective way of blowing two-fifths of a standard army. I'm not saying that she's a waste of points (I'm sure than in a Roman build, she'll be used to get your soldiers turtling very easily even after some wounds have been put on them), but I would think that more soldiers would be better. Or at least more durable Warlords.
