I am not Cav but I will reply in hopes to help you out!
Actually, some squads have gotten on Game Battles BUT, we have the same type of thing with
www.ClanCompete.com.
That is an online gaming site for any and all clans to compete in all online games.
It isn't just about XGC, KoG or SYN. We have several teams not in Xiled Gaming registered and playing in matches.
We just started a new season for matches in HALO 2 a couple days ago.
You should go check it out!
