We r talking about supers not swords and shields. It should penetrate because 1. GG only gets one shot instead of three which will not be necessary in most scenarios. 2. After GG there is a delay for pulling out a weapon while the guy in the bubble will already have their weapon out. 3. A Titan will have blessing or weapons of light until the bubble goes away. 4. A GG does not get an overshield. This means that it would be more dangerous to take down a bubble than sit in a bubble 5. A GG can also get shutdown from a defenders suppression nade. However, it should take 3 GG shots to take down a bubble.
