I've been using a Levithan's Breath double special build with traces rifles and rocket sidearms since The Call came out and it's the most fun I've had in the game, especially once I got my HOIL class item for constant ability spam. The build still works and I've tried other since the release of this expansion, but nothing feels as fun. Just sucks to know that I can't level up as easily in the game because I don't play the way they want me to play. Though right now I'm waiting for that stasis rocket pulse with chill clip.
