Interesting! Really close to a build I'm using in my titan. Monte Carlo Shotgun Heavy of your choice I took speed instead of recovery because force barrier is almost always active, so there is no need to recover(still need to upgrade my Monte Carlo for the reduce melee cooldown perk so that "almost" turns to "always"). And Blessing/Weapons of Light instead of the inside bubble shield, along with the increased benefits of those perks(Illumination I think?) Super fun build. I just wish the Titan's melee animation was a bit more epic. Too many right hooks. It'd be cool if they added a few more animations: left hook, uppercut, haymaker, etc. and you randomly got an animation.
