Nerf

"Nerfing" is the term used by players of online RPGs (not just Guild Wars) to mean the reducing of certain content's effectiveness that the developers of the game have deemed unfair or an exploit. This is usually done by releasing an update for the users to download. There is no way to avoid a "nerfing", as all content is automatically downloaded on startup of the game. Nerfing is most commonly used when referring to certain builds that are unfair, especially the farming Monk build.
