Finally found one, and hired it. Matri, so not sure how useful, but still. I used to look for Kenny, but not anymore.
She's really good until you get to the AoM areas, Then she tends to die too fast. But I like her a lot and even paid to unlock her for when I adventure in areas lower than AoM,
I've got Matri on two characters, she works best with my Warden to back her up. Kind of a glass cannon once you get into AoM, not too durable on her own. Merc shrink is nice with her. I've never looked for the Elites, just happened to find her twice. Not really interested in the other elites.
Don't give up. I got both of my Matri about 3 weeks ago in the span of 4 days. Was just shiny hunting.
