Forum:Mirage Arena?

Hey Guys, I've Owned KH: Birth By Sleep a while now and I got really excited when I found the Mirage Arena and found out about the multiplayer mode, only problem was, I could never find anyone who was in the Mirage Arena with me to fight in Arena Mode. So I've done Matches 1-11 on my own, but now I'm at 12 and...well.... playing with a friend would be really nice haha. So I was wondering if the Arena is always like this? Have I just had bad timing or is there never anyone else there?
