One of the hardest things in World of Warcraft is finding information about PVP. There are a lot of reasons for this. First the PVP changes constantly. Second, PVP is dynamic. There are no universal tips that make it easy. What works for one player may not work for another. However, if you do everything properly and learn your way around each of the character classes, eventually you'll dominate PVP in ways you never thought possible.
