I need some variation in my game, give me a new build!

Howdy everyone. I've been running very smoothly throughout the game as an Overcharge SAW user, but unfortunately, I'm getting rather bored of it and I'm looking for a good replacement.

I'd just like a build that is effective in PvE and more-or-less useful in PvP as well. Anything is fine, so feel free to link me your excellent set-ups.

Current level: 720

From what I hear cloak and shotgun get the job done
