Don't know why I thought of this, but let's have some fun.  Please realize that I have only been playing for a little less than 2 years and I really only know North American players, and I don't know what tweaks they may be using, but the best players I have watched and played against are:

1. Flux.  He also goes by Fluxxx and FX.  He is also Canadian, so that's cool.   I have never seen him lose.

2. Daknasta. I might have butchered his name...lol.

3. NFRS

4. Titan, also known as Pingalicious - never dodges, uses a gamepad and mouse and wins almost all the time in public servers.

5. (Rot)Exodus and TROG  Tied for 5th.  Yeah I snuck in another name, its my question  lol.

You play the most. You know the best I suspect. Helen, doesn't make this list? I consider him pretty freaking good.

Okay Helen,
Well played!  I do have to agree with numbers 2,3,4 and 5.  I'm a pretty quick learner for a fat guy in a skinny coat, that kids tough, using one hand,well that's pretty cool, and Blitz should be called the energizer bunny!   

Number one might be a stretch. That guy's a server admin. He makes my bots Godlike and his novice.......Not to mention when I finally pass him for points he has to mysteriously shut down the server!  lol.

Yaeh, I was all upset when I found out he was letting me win most of the time. He likes to laugh at me because I charge forward even when I know you have already dropped some grenades for me to run in to when I get around the corner. He real Cruelllll like that. He even types it out the LOL and stuff. LOL.
