I would say about 40 percent of the time my full auto shotgun gets the job done. Also a lot of Titans run blessing or weapons and so aren't nearly as tough as the ones in the bubble with armor That said, I don't do it a ton If the bubble is well placed and it could really hurt the dynamic of the match, like for example C on blind watch, or A on Delphi, I will take the chance. The other thing I do is if I know I'm in trouble I will run in and drop a lightning grenade on the floor of the bubble Yes I'm going to die. But with aftershocks and 4 pulses it's likely the people in the bubble are either going to leave or die too
