Everyone has a different idea of what the perfect rogue consists of. I know plenty of rogues that wouldn't play the class without its subterfuge and stealth tactics. Other rogues focus entirely on our combat mechanics and couldn't care less about our burgeoning bag of parlor tricks. There are PvP-focused rogues that will never Pick Pocket their targets, and there are PvE-centric rogues that have no idea that Shadow Walk was ever introduced.
The question is what makes us play rogues? What would make new players try out the rogue class? Every player has their own reasons for picking the rogue over the other classes. What changes could be implemented that would bring in more players? Ghostcrawler has indicated that the relative power isn't correlated with our population stats. If cranking up our damage by 20% wouldn't increase the number of active rogues, what would?
