Yes, nova bomb can. I've done it. I've seen it done. And I've died from it. Your argument about that is moot due to my first hand experience with it. You won't win me over there. GG takes 3 shots to destroy a bubble. So you use it up, or only have 1 shot left with the proper helmet. I can't comment on the hammers vs a bubble, I've not been privy to that yet. As for striker, ha. The only part of striker that could go through a bubble was the arc line, and they nerfed that along with that happening on blade dancer as well.
