Okay okay. I tried this with some friends and I saw a rather intuitive way this was countered by two hunters on the other team. They got there super, had vanish perk on, went invisible and both ran into the bubble and -blam!-ed everything up. It's counter able, just not gonna help you out for the rest of the match. The trick is to disrupt everything before it starts, you HAVE to be aggressive and never let the team group up. This strategy beat my team that used this coordinated super strategy.
