I played like 5 strikes before I figured out what the hell that was. I was like wth is killing me. That is by far the number one annoying thing I've seen ... somebody must have won a bet and were able to add their input to the game. Horrible.
Sounds like a skill issue to me. If you actually pay attention in the strike, the bombs hardly ever get you. They're actually really easy to spot, too; just gotta slow your roll for three seconds and look.
