Actually, MB, that isn't close to being true. The Want It, Need It spell is a highly focussed and limited bit of magic whose only effect was to give everyone who came into contact with Smarty Pants an irrational need to possess it (to the point of violence). On the other hand, the Fiducia Compelus spell is much broader and less limited in its effect. You could hypothetically use it to make somepony do almost anything and maintain a high level of control over them at all times.

One of the reasons that Lesson Zero ended in a riot is because Twilight couldn't control the consequences of the spell, whilst, on the other hand, Starlight's spell is far more dangerous because it is all about controlling others actions on an unlimited scale.
