I have never really thought anyone was amazing, I have played with some high ranking players but they never seem to face me too much. I think there are two people I remember the most.
The first is
http://bf2s.com/player/57808211/ (odsketcher) because he was just so flucky with his shots. He is my worst enemy, and my mate who I was playing with is his. It was just the way it went id hurt him badly he'd somehow kill me and my friend would finish him off.
The other player I dont remember to well he was a dutch player and his name was vander something. He managed to kill me and my friend so many times, and he would just pop up from no where.
As far as the player I respect most, that is one of my clan mates, McCroft. The reason is he is a great guy and is always trying to improve his playing. I have had lots of laughs and some great times with him. I always kick his ass, but he is always there again trying. He also works very well with me as we know each other well. That being, he also trys to cut me off on maps as he normally knows what I am doing, so it makes all the easier to kill him as I dont have to find him :-P
