^Did you know there's another prestige with 2 different symbols as well? I saw it today some guy was a high stiege and I went to look at his combat record. His prestige symbol was different from his prestige emblem. It was like a circle with a lighting bolt through it or something like that. I should have taken a pic or something.
I can confirm this as true. The 13th prestige symbol is the one you're talking about. It's actually a torch surrounded by a black circle. I have to admit it doesn't look very cool. Hitter and Jayson from Wii Unite are both on 13th prestige so that's how I was able to confirm this.
