Bindings and Movement
Movement is an enormous part of this game, and I’d argue it’s more important for rogues than any other class.
Bindings
The first and most important step in improving is to bind your keys. If you already do, great. This is the paramount, first step on your journey to success in game. Look at it this way, if I had to choose between 5000 attack power and having unbound keys, I wouldn’t have to think twice to choose bound keys. I think it’s ridiculous for people to invest countless hours into this game without binding, it’s the equivalent to fighting with one hand behind your back. I often hear the argument that clicking is a choice or you can make it work. I can spec 20 / 21 / 20, kill people and it can work, but it’s far from optimal.
Once you bind your keys you should probably unbind turn, its a waste of good key bindings (there is no reason to have it bound). Your primary movement should be using strafe and your right-most mouse button, combined with the occasional use of forward (default “w”) and strafing. Strafe often, strafe is your friend. In almost any situation where you can back-peddle (s key) you can simply strafe instead (while turning with your mouse). Using the ’s’ or back key is the equivalent of applying hamstring to yourself, it should rare if even be used.
Originating (presumably) on the World of Warcraft forums, this is an essentially derogatory concept some people employ that means that all that a certain class must do in order to achieve success in the game is to bind every key on their keyboard to one ability that is perceived to be overpowered, and then continue to roll their face across the keyboard. The notion is that this one ability is so amazingly overpowered in relation to those of other classes, all one has to do is absently spam it as much as possible (and they might as well do it with their face, because there isn't any other use for the big stupid thing on top of their shoulders).
How much can you fucking suck at it
