Iron bear gunner spec

Been playing as an iron bear moze build since i started bl3, and i think the honest truth for this build is that loot drops become less interesting, something to make IB more interesting and honestly either give iron bear loot drops or letting it equip heavy weapons would fix this, the other little thing is dakabear letting you sit on his back in the turret and fire your own weapon/lob grenades with ammo and health regen like the ol scorpio turret, would be fun.
The last change id like to see if iron bears melee attack knock back all the time to get melee enemies off you.
If i had the first thing i think this build would be more enjoyable.
