I had some spare time, so I tried making a BiS list.
As I am a Alliance myself, so I counted Heroic Presence to be active.
So here it is:

Idol: Idol of the Lunar Eclipse (http://www.wowhead.com/?item=50457)
I did not make this BiS list with a dps calc or something like that, purely based on what I thought what was the best item.
If you want to see the stats you get with this, here is the profile for it:

As you see, I did not include gems or enchants, since they may vary depending on your professions.
