Her Fusion guns require her to operate a little too closely for her Stealth Field Generators to be used effectively, and wound/save allocation means you have a good chance of killing that Command Link Drone with a bad roll. They tried to mix a support type commander with an offensive type, so she suffers from a usefulness disorder, and does neither particularly well.
Not only that, but her helmet looks silly modeled on her, thus driving the final nail in my decision not to run her. I never use "un-helmeted" heads in my army...
