Most played Grifball?

So, I was looking at my Halo 4 Overview here in the Halo 4 career section and I noticed something. Not a very big problem, but does anyone else’s say their most played variant is um…Grifball? It said slayer on the first day, and I tried Grifball by my self for maybe 15 seconds, just to throw the ball around. I was just wondering if anyone else encountered this not so game breaking, not so problematic little problem. You can even see in my number of Wargames custom games iv’e played.
