This happened to me several times today in The Crucible on Control. Defense Titan pops their bubble. Ok, I know this game...I'll wait out here...inside is a death wish. I get a little distance and pull out my sniper rifle and just wait for the bubble to end. Every non titan in the bubble always gets the bright idea "Oh I'm gonna go one shot that guy with my fusion rifle and jump back into my bubble before he knows what hits him!" The second that head popped out of the bubble, BLAM! HEADSHOT! I know I won't survive a rush from everyone leaving the bubble when it pops, but God help you if you step out of that thing alone...
