I tried a new strategy on a team in a bubble and it worked better than I even expected. I saw four opponents in one over a zone. To draw them out, I blew a kiss at them from about 30 meters away. The Defender [i]immediately[/i] came charging after me with a shotgun. I ran behind a corner and hit him with my fusion rifle when he appeared. I killed one more, then a teammate showed up and we killed the other two (they seemed confused when their bubble vanished). It was beautiful.
