Why do "Standard Controls" players still need to face target but not "Legacy Control"

Just use Legacy controls. Will it be a bit rough early on? Yeah but then it’ll click and you’ll wonder why WoW doesn’t have this.

I mean..wow doesnt really need it. you dont really have to fight against the movement in wow in order to hit the target. having an attack cone of 180° is nice. But both gams are built around their own movement.
