I understand that I am probably somewhat of a noob, but I have come a long way already. I do know a lot of the jumps and moves. No, I don't know them all, but I watch what others do and I do most of it. The thing that gets me is when every time I'm just moving into view of someone else, at full speed and everything, they shoot me with out even trying, so I'm like "what? gotta be some cheating going on here." Doesn't happen with all, but a lot of people it does. Then other games I'll be playing and I'll be wasting everyone. So that's why I'm checking to see what the percentage of players are that do cheat. However, this poll is probably somewhat skewed because it is only the more devoted players, which are probably those less likely to cheat. So if I were to consider, based off of this poll and the idea that most here wouldn't cheat, there's probably about 20 to 30 percent of the players that cheat, which means that in most games of more than 10 people, there are at least 2 or 3 cheaters in it.
It is probably not cheating in most cases. It is routinely the talented players that dominate, and it is predictable. When you see certain people in a server you know they will have a high ratio the majority of the time. Once you know who they are you will realize why you sometimes own and sometimes not. You own when the consistently good players are absent. You get owned when they are present.
Most cheaters who are good players are looking for a little edge on the competition. Your experience probably derives more from a gulf in talent and practice than your opponent cheating for a slight edge. It comes with time. And for some it never comes. Some just don't have the natural reflexes or hand-eye coordination necessary.
I for one have sub-par aim. So it is no surprise when I die quickly against talented players. I may get lucky sometimes, but a player with good aim will shoot me first the majority of the time. That is just life.
Having said that, cheating is a problem. It is unclear how big of a problem right now. Some say many people cheat. Jits contends it is far less than some claim.
