Yeah, that seems like how I'd picture her fighting.  She probably also hits stuff with more power since it's been established that she's got the most experience.  

So, to assign people general classes because I'm horrendously geeky like that, we've got a warrior, a rogue, a machinist, a sniper and a warrior-rogue.  Howlite has pretty much been established as a berserker and Amber seems like a straight up warrior with some tank tendencies.  Did I forget anybody?
