"To arbitrarily, inexplicably buff or nerf a class in WoW PvP, often at the expense of another class."
To be "Kalganized":
Being Kalganized can be good or bad depending on whether your class got nerfed or buffed. If you got buffed, its good, if you got nerfed it is bad. To be Kalganized is when your class either completely owns another class in a way the class being owned has no defense against or being completely owned by another class in a way that your class has no defense against.
