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.

No we just need sub class customization so we can have wol with bubbles instead of it being strictly on bannersheild.
