Edit: I like how long ago this was and I'm still surprised to see it as a sticky Below is a jumbled mess of a post 3 years ago, and I barely know what I was trying to do for an OP. Just post your mog or things that look cool for a Mage and ignore my OP being all "HEY, I LOVE SEASON 8 GEAR!".
NOTICE: The staff is supposed to be blue. Wowhead's 3D Viewer is a little buggy sometimes =)
To view the items, click the dropdown v arrow under "Save", and click "View in 3D"
Also considering http://www.wowhead.com/item=28633 for the weapon, as well as http://www.wowhead.com/item=19355
EDIT: I've actually changed my set (RIGHT after I got full T2 also >_>). Leaving OP up because it kinda helps others get their sets to show off if too lazy to post an SS =)
Decided to go with S8: (PS: No, the P1 Legendary staff is NOT part of the set. It will either be the P3 Legendary [Since I can't transmog it] or another staff I have not yet obtained yet >.>)
(Reuploaded due to apparently I was using my S10 gloves >.>)
