@34975634954957 I don't main her (still mastering everyone), but love playing her & mastered her a while back. I chose her for this week's character challenges & was quite disappointed I got them all finished in 2 games of Ops, as really enjoyed playing her again!
I think of her as a lot like Rose - very powerful, once you've got her range right & also dramatically improves as you level her up.
The Disco Tornado is a great tool for taking health off a group, it's just a question of timing the activation of it.
Funky Bouncer is incredibly useful for pushing attackers away from you or from objectives you're defending - great fun in Ops sending AIs off the edge of a cliff in Weirding Woods or Rocky Flats!!!
Not much help, I'm afraid - but hopefully one of the guys'll be able to give you better tips!
