It has changed the perspective of people playing the game so when they are killed when they are trickshotting they consider them randoms when really they are playing the game it was ment to be played.
The comuntity has changed in many way now if you get on with a Gamertag thats xxM1gPr0xx people automaticly call you bad no matter what that never happened in 2010.
Skid refers to a 'Script Kidde', someone who steals code from people and implements it into their own programs and claims it their own.
OT: Quickscoping/Noscoping/trickshotting is all based on luck and how the game engine responds to your shot. Aim correction is an overpowered exploit in the game. Turn it off and try to trickshot.... We will see what happens.
