Best raiding spec for MoP ?

[Rakash]

So i am kinda bad with Simcraft and how it works. And i don't know if it takes account with movement etc.
So i was wondering if there is a flat out best raiding spec in MoP ?
Thanks

At the moment Affliction using Grimoire of Sacrifice looks too good to be beat in most situations. Exception: Demo on large scale AoE followed by Destro. I can see specific events where burst would be important be good for Destro, but the other 2 specs would be almost as good or better, depending on exactly how long the burst window is. On the whole though, I'd say go Affliction with GoSac and hope we don't get nerfed.

EDIT: should also mention that on very heavy movement fights Demo will probably come out good to, cause most of what you do in Meta is instant.

Basically what xskarma has said. Affliction is just WAY too strong at the moment. Early simcrafts put it way ahead, but remember this is wayyyy early http://simulationcraft.org/505/Raid_T14H.html
