It's especially useful as a left-handed gamer. Right-handed gamers have the mouse on the right and use WASD for movement—and there's a comfortable distance between the two. Left-handed gamers have the mouse on the left—using WASD feels very cramped. The benefit of using WASD for movement though is that there are a plethora of keys in its vicinity that can be remapped. With the numpad, not so much.
