I destroyed her as a lvl 30 assassin in mixed gear (Greens / blues / oranges) FYI. It's just a l2p issue really. Jolt - Electrocute - Channel the force - Jolt - Electrocute - Jolt - Overload - Jolt. You can keep her from casting pretty much the entire fight, once you get further down the line and start going into a panic, that's when you save whatever interrupts you got left for the force storm. Edit: Funny you should mention Huttball as the only good thing, seeing how that particular warzone is the most pathetic piece of game design i have ever laid my eyes on.
