Ran into this last night during IB with a completely random team I was on, this strategy didn't work long for them though and there is a few reasons why. 1. Our team wasn't full of idiots who kept trying to rush bubbles and golden guns, we were smart enough to not feed them kills. 2. We didn't waste our supers besides when the shields went up, we weren't idiots who blasted supers off randomly when we knew what tactics the other team was using. Now remember this was a match made team I was on. The bubble tactic didn't even last half the match for the other team because every time one went up two supers on our team activated right away. Took down the bubbles and killed everything even the GG's. If a match made team can figure this out then there is no problem with the tactic as it has an easy counter, however stupid people will continue to do stupid things never learning new tactics... How did Einstein define insanity again, oh yeah repeating the same steps yet expecting different results.
