I feel like this would be great to make Defender Titans up to par with the other supers, but I think the only way this would work, is if weapons of light was used. And by that weapons of light would allow the bullets to pass, but at 25% reduction, but I you stepped out, it would work as a normal buff. It wouldn't be OP because they still can't leave their bubble if they wanna do dmg from inside of it. The super is meant to defend you, and I think the fact that it doesn't allow you to be offensive while keeping you safe kinda makes the super a super magnet, or an invitation to walk in and get ganged lol.
