I have been having great success with this build, especially in CW. Plays a little like gauss vomit actually, hot as hell but can be managed by falling back on the big boomstick for a while.
I use this exact build as my daily driver. I absolutely love it. Its a beast. That alpha is nasty, and yup, falling back on the AC when you're getting warm keeps you dealing damage, even as you retreat for a cooldown.
I had a similar build, but with SPL instead of ML. Main difference is ammo count and AMS instead of BAP.
