So hopefully most of us are at 1000 valor by now, and should be *honored* with Golden Lotus either today or tomorrow.
So, what do you want to spend your valor on? They are:
Klaxxi - Legs - 2250
Golden Lotus - Ring - 1250
August Celestials - Bracers - 1250
August Celestials - Boots - 1750
Why these pieces? Simple: some dumb-shit employee at Blizzard neglected the fact that Mogu'shan Vaults does not drop any Legs, Rings, Bracers or Boots for Mages and Warlocks!
Therefore, if your guild isn't going to give Mages/Warlocks spirit gear (which they shouldn't), the above will be our BiS going into Heart of Fear and Terrace of Endless Spring.
The week those raids open, we should have earned 6000 Valor. The above costs a total of 6500 valor. Which means you might want to consider grinding out that last 500 valor before raid on Tuesday, Nov 6.
Note: for your second ring slot, there should be a Klaxxi quest chain at Revered or Exalted: Shadow of the Empire to get you a: Seal of the Lucid
edit: I meant you should be honored today with Golden Lotus
