**DISCLAIMER** - This spec & rotation are primarily deisgned for heroic tanking. For raiding, Blood and Frost tanking specs produce approximate 3-5% more threat (not saying you can't raid with Unholy, just that other specs produce more threat )

The spec / rotation that was viable for 3.22 has changed for 3.3

New spec looks like this:

Note - I have gone for a non-Reping spec (i.e. no Death Runes). If you want Reaping, I would suggest this spec:
http://talent.mmo-champion.com/?deat...Z,Yp3eO-,10676
Please note this has a different single target rotation (the 2nd round of Blood Strikes get replaced with a sinlge Scourge Strike).

Rotations have changed since 3.2.2 as we now take Epidemic, making diseases last another 6 secs - in other words you only need to refresh diseases every 20 secs (every 2nd rune seqence).

You may need to add or remove commas depending on how quickly you mash the keys.

Hope this helps...
