Personally loved the silverish/grayish color with cyan. Problem is that the dye is nowhere to be found in the game, at the moment. It'll be nice to see it in the Cartel Market or to be crafted.

I would not use her as a dps companion because her only two offensive abilities is a dot and some charged shot. The rest of them are healing abilities and a channeled stun.
