Honestly its the same handful of guys screaming cheat all the time. I really love owning some chump who is clearly lacking in skill and then they start screaming on 200 that I just pulled some impossible move when it was a trivial kill on my end. I don't pretend to be close to the best, but these guys need to realize there are people who play this game that are so much better than they are, it may appear to be cheating to them because they are ignorant of the full potential for how the game can be played. There are specialists that have had so much practice, they can pull off some amazing stuff.
Situational awareness and pure experience is the true cheat code.
