Nerf

"Nerfing" is the term used by players of online RPGs (not just Guild Wars) to mean that the developers of the game have released a patch that fixes an exploit in the game that people like to use. 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.
