Ok, the score was 49 to 37, and I had 19 kills and no deaths, so naturally, I was hoping for a perfection. I has just killed an enemy sword wielder with a DMR and grabbed the sword. I noticed 2 enemies were about to come around the corner, so I wanted to lunge one and end the game. I targeted the enemy in front and I lunged. The second enemy almost parallel to the first went into armor lock, and for some ridiculous reason, my sword seemed to be deflected by the armor lock. He popped out, and I got double pummeled, costing me the perfection. What the KCUF!!! I was 100% positive the aimer turn red on the first guy.
tl;dr lazy version: Does armor lock have a larger area of effect than I realized, does it attract you towards it, or was it just some freak lag (everyone had a yellow connection bar)?
