Articles on PvXwiki contain both facts and opinions. This is a good thing, as our goal is to be a guide for the game and often both kinds of information are useful to the reader. For example, we have not only raw data on a skill, but also best practices for using that skill, good combinations with other skills, commentary about why the skill is better or worse than another, and builds that incorporate that skill. Such a comprehensive treatment of a subject is one of the strengths of PvXwiki.
