"Melee Shifting
As I’ve been following the ongoing debate over melee shifting, I must confess to being a bit disappointed. In the past we’ve addressed the exploitation of bugs as contrary to the spirit of the game. Players should operate on a level playing field, and only skill should determine the winners and losers. Taking advantage of an in-game glitch that gives an unfair advantage over other players or makes weapons behave in ways they were never intended is not “skill,” it’s cheating.
To put it in plain language: the Combat Arms Team considers shifting to be an illegitimate play tactic. We’re currently working on a way to eliminate the bug that allows it, but until that time, melee shifting will be considered a bannable offense. " -Nexon America Inc.
