It is arguably the worst path of any subclass and with the addition of Well of Radiance it seems even more worthless. In D1 you'd need two Titans to achieve the same affect as that super, so I have a solution. Make it to where you can shoot through the bubble and it gives a slight damage boost not as much as Well, but close enough. Well should offer more damage and bubble should offer more survivability.
This leaves the new commander path as useless, but just giving that a massive damage buff would justify using it over the new Ward of Dawn. (Even in it's current state it is worthless, since you do more damage by shooting) As it stands two thirds of Sentinel subclass are "useless" (very gimmicky) in PvE when they should be the strongest for the Titan. Either one of those would work, but both would be preferable.

Code of the Commander is one of the most slept on new supers. For both PvE and PvP. Void detonators are so strong, health regen and ability energy, even in crucible this shit spreads like wildfire. The super is also amazing, only thing that can successfully block blade barrage and yes it does happen. Especially useful in gambit when being invaded.
