Set bonus' are weighted fairly heavily (2pc T13 at 170pp), so unless the itemization of an item is way off or there's a large Ilevel difference, it's better to keep your tier bonus intact. The most effective way to do this for T13 is to use Gloves for your off-piece, since liquid smoke has a higher ilevel. Also, as ultimately you want tier, planning your VP purchases saves you time. Buying the neck (arguable as reg chock is easy enough), cape, and wand are your best bet. While on the other hand, avoid the belt, chest, and helm.
A few points for improving:
-You're also over for hit, always aim for slightly under the cap, you waste any itemization over 17%. I'll run 16.5% or so and go whole weeks without a miss.
-Get a PT or at the very least Hurricane chant. As shadow, we can artificially extend the benefits of these procs by appling VT and DP right as they expire, garnering a significant improvement to overall DoT damage.
-Replace the Hymnal trink with pretty much anything, it's the weakest of all the 346 trinkets. Consider getting the Valor Trink, as even tho it is lackluster its a phenomenal trinket for Spine of Deathwing, and can be a good stopgap until you can get your Will of Unbinding to drop.
