Damage potential. Out of Q W E, Q will do more damage if you hit with another spell after, and E will do more damage if you land both halves of it. Combine that with the % multiplier of R, and there's a notable gap in how much burst your combo holds.

Not to say you should always Q R, but that's probably the reason.
