Where are all the other XBOX LIVE gamers that apparently play Soul Calibur 4 all the time too?

I play Soul Calibur 4 just about every day and try to squeeze in a match or two between classes and work. After work and during my longer lunch breaks I play it, and I always see the same gamertags. I've been doing some online searching about Soul Calibur 4 on xbox live forums and I keep hearing about this guy named leofire who is supposed to be extremely good with Taki, but I have never ever seen his name come up since the day of the release of this game. Also, I'm in the facebook group "Soul Calibur 4 online community" and a lot of members list their gamertags and I have never ever seen them before. And I play A LOT. believe me. to name a few gamertags I see all the time: (may not be exact)

Well they realized that Soul Caliber sucks and they moved on to Street Fighter 4.
