I can see a Striker and a Warlock coordinating to screw this whole thing up. The majority of the time, its one hunter using his GG. Wait out the four shots as it takes time for him to run back to pick up orbs, as well as get through the animation to activate his super. Once fourth shot is fired, warlock nova bombs the bubbles to make the group panic and draw the fire of the Hunter if his super gets off in time. All the while, the titan sprints up the middle and uses FoH on the Defenders bringing up the bubble again. Strategy. Killed.
