I disagree. All the supers in the game are designed to counter each other. Defender bubbles insanely good if other team doesn't have a super ready but it makes sense that a super can be bested by another super. Any way you look at it your still forcing the enemy to burn a super on your bubble, and if your the only one in it I think that's a good thing for your team since a super is used to ideally kill 2-3 people
