Ghostcrawler recently described the rogue class as "slippery". He was met with a backlash of rogues arguing every side of the argument. I have personally struggled with my mental image of the rogue class. What does a rogue look like? Are we lightly-armored thieves or toughly-bound brawlers? Let me get this one out of the way early: "A rogue doesn't look like anything because you can't see them!" While I appreciate Stealth humor, the quip doesn't answer my question.
Appearances have always been an important aspect in WoW. Players used to gauge their opponents' strength based on what shoulder armor they were wearing. Transmogrification is easily the most important feature of the past few years, as it has breathed life into content both old and new. The rogue class draws from several diverse archetypes, such as the thief, the assassin, and the brawler. Each source archetype contributes flavor to the class, but the end result can look like a confused mess.
