Masters of Mellka! Share your helix builds, loadouts, tips and tricks!

I think I just found out who the coolest, most awesome-st Battleborn is and I want to be as amazing as she is when I'm playing her. I found some videos on youtube by Kiratze who's got a pretty cool way to play her, but I'd love more feedback from our community here to see what are different ways people kick ass using Mellka.

EDIT: I'm mostly interested in PvP, but won't turn down PvE knowledge as well.
