Pvp mage skill build pls?

By upgrade i mean by the name it should always have Magic Missle [1].
I say not to upgrade Magic Missle because if you upgrade it the Cooldown increases from 4 seconds to 6 seconds I believe.

For instance:
Magic Missle [1] - Cool Down 4 seconds

Magic Missle [2] - Cool Down 6 seconds

The other skills you need to upgrade. They have no specific cooldown switches like Magice Missle

Magic Missile 1s CD is 1.8 seconds...

Magic Missile 1s CD is 1.8 seconds...

xP I wasnt in game so I didnt feel like checking...
Is that with complete cd? Or before you ad points?
