What's the most optimal Unholy AoE talent build?

I'm currently at 5.1 Dps and I mainly run dungeons and a little bit of ICC. My single target build consisted of 0/3 morbidity, 3/3 BCB , and 2/2 Dirge.
For my Aoe build I was thinking of going something like this http://imgur.com/a/VTKwp. But since I'm no expert I wanted to hear if they're are better suggestions.

Take Corpse Explosion and Dirge over BCB, equip 4pT9 and that's pretty much it.

For Dungeons:

DPS while in Unholy Presence.
Glyphs:
Major: Death and Decay, Icy Touch, Dark Death
Minor: Pestilence, Corpse Expo,
Rotation: IT > PS > BS* > Pesti > BT* > DnD > Corpse Expo/DC
If u dont have BT just skip BS*.

For Raids:

Read the guide for Rotation and why these talents.
