Having a hell of a time setting up bars for my gunbreaker. I can't find anything that fits neatly and is comfortable to use. Suggestions?

I play with controller.

I typically keep ST on right face buttons and aoe on left, but there's too many abilities to fit in those. Left dpad is hard to hit while moving so I put stuff I don't use while moving there.

This is really hindering my enjoyment of the job. I want to like it, but I just can't when stuff doesn't flow, yanno?

TIA.
