You can be a mediocre rogue simply by pushing three buttons. While that might seem shocking, remember that you can be a great mage with just one button. There's just one problem with being a rogue who spams Sinister Strike blindly -- you're not using all of your capabilities.
Rogues have a rich culture of maximizing our damage at all costs. Rogues are a conceptually simple class. We only have the capacity to deal damage in melee range. Rather than letting that stifle us, we embrace the purity of form. Every single ability that a rogue wields is designed for a specific purpose. Our talents are designed around a single paradigm: kill. As you being to unleash the full arsenal of the rogue, it's easy to see why we're so efficient -- and why we're so feared.
