3 mages and a priest

Recently I wanted to make a 4x shadow priest team, but I got discouraged, so now I was thinking of going x3 arcane mages and x1 holy priest,(undead). So basically I have resistence to fear because of racial and trinkets, also mass dispell, and if a warrior or rogue, or whatever melle classes get close to me, I can simply spam AE, since illbe arcane spec I can expect nice dps, and for distance fighting I would use arcane missiles and the new 51 arcane spell, it's 1000 dps, plus spell gear, times 3 mages so the dps would be awesome.

And the holy priest would probably keep me alive for a very long time.



So what do you guys think of this combo.

I'm going to toy around with 3 mages myself. So far Arcane Potency has not been nerfed or removed, so if you pop POM and just stick to instant casts like Arcane Barrage, fireblast, nova icelance, CoC, AE, ect you'll have a bonus 30% crit until you use POM up or it's dispelled. Definitely going to be some major dps with that, so of course I'm expecting the nerf soon so I probably won't touch deep arcane if they do.
