Personally I’m thinking of three ways of making the bubble viable. 1. Unleashing the Ward makes a suppressing wave to use as an offensive option. 2. Equipping Offensive Bulwark with the Ward gives increased grenade energy similar to Sunbracers, so Titans can feel comfortable choosing any grenade and not feel forced to use suppressor in both PVP and PVE. 3. (This one is a bit crazy.) give the option to carry the bubble with you. The bubble will be smaller, weaker, you have reduced movement speed and cannot lift,but you can shoot though it and generally give you more health than any buff. Like the original version of the Icefall Mantle.
