Should I wait for a 5 or 6* ghost, or is she good on her own?
She doesn’t need ghost. I often use her more than ghost too. She has a nice passive stun which makes for easy heavy chaining in the corner, high damage, a handy concussion, power stings, and a lethal sp3 ramped up.
Thinking long-term, torch would be the better option. But I'm assuming your 5* covers your torch needs for the moment, and a sig200 void is pretty useful.

Great for a lot of act 6/7 bosses, and a top tier AW attacker. Makes a lot of problem fights a breeze.
