Looking at it, with max CR so she only costs 10 UP. She certainly has a role as an early ganker/UP generator vs fast ground units. Plus you get more points back when she's withdrawn. Or you can drop a soldier/archer if you have the time and UPs.

Not sure if I can be bothered leveling her or not. If I can get her to 10 UP deployment she's a handy tool in the arsenal for her cost.
