- you have all your abilities bound to the numpad
- your right hand is at the numpad and occasionally switches to the mouse if need be
- what exactly is your left hand doing? Modifier Keys? Movement?
And why should your right hand be in the middle of the keyboard? It normally rests comfortably on the mouse if you play with the numbers.
I'm a little bit confused here...
If I remember correctly I played with the numbers and wasd too in vanilla. With the two modifiers it was a sufficient play style, though after my second break I overhauled my interface completely and now I'm really happy with my keybindings and mouse movement (and I would not be able to fight a single mob without my addons, but that;s another story...).
