It's probably done in part for the sake of other people in multiplayer to show that you're doing something and not just AFK. I can agree that combining the animation into one which triggers upon casting is a good idea.
Perhaps when deciding what spells to cast, a slight shift in stance and a glow would suffice as in indication.
