It only came to my attention after the match because I was doing so well... A Titan was running around with Juggernaut while Shoulder charging. How is this possible? The shield was up all the time! Now forgive me if I've overlooked an exotic which grants Juggernaut. To my immediate knowledge there isn't one. Nor is there one that grants Shoulder charge. Again, I didn't notice until the match was over because my team was absolutely wrecking theirs.
