Remember Dark armor has oppressive gloom, which disorients everyone around the user- similar to drawing Blackwand, no? I see Vlad as a scrapper, mainly because a katana is also a light sword, his reflexes, *and* the fact that all scrappers can now take a pool with shuriken in it. Aliera could also be an empathy/energy defender- empathy for healing, and the fact that she uses some sort of energy attack against Mellar's guards in Jhereg. I see Kieron as a Broadsword/Invulnerable scrapper. Sethra is a bit unique- I don't remember ever seeing her fight. All we know about either her preferred or usual techniques is she has Iceflame.
