I used to read a rogue blog called World of Ming, where a rogue named Ming would explore our class' capabilities in the world of high-end PvP. My favorite posts were his deep-dives into dueling. Ming had the belief that the rogue class should be able to defeat any other class in a series of duels. If you wanted to fight Ming, you just needed to log onto the PTR servers to find him dueling outside of a major city.
Blizzard has often claimed that WoW simply isn't balanced around 1v1 combat. In fact, even the 2v2 Arenas are considered to be a lower tier of competition -- complete with lower compensation. The 3v3 and 5v5 Arenas are heralded as the truly balanced PvP platforms. In spite of Blizzard's disclaimer, the fact is that many people consider duels to be the ultimate form of PvP. The rogue-vs.-rogue duel has long been held as the truest test of skill between two brothers of the shadows. If you ever plan to engage in a rogue duel, you need to know about the sacred code of dueling conduct that every rogue should follow.
