I've done a little testing on mobs in Frost Gorge. With Omnomberry pie (66% on crit to steal health) and sigil of air, even auto attack damage is ok. I think there is potential for it, especially if you use Shadow Strike. It hits for 3-4K and if you can work it into an attack sequence, damage should be pretty good.
Edit: Some initial observations:
Sigil of Air
is hitting every ~5 seconds for 1.1K-1.4K.
is hitting for ~925-1.1K when it crits. With the Omnom pie, there's a great chance it procs for an additional 325 damage (which also heals you.
is hitting for 3-4K when it crits. With the pie, that's a potential additional 1625 damage, that also heals you.
Cloak and Dagger
is still hitting for 3-5K on average with crits.
is hitting for ~800-1.1K for first attack, 2.5-4.6K on the second portion of the attack when they crit. I'm typically seeing an average of 5.5K if both crit.
from Vital Shot and Sneak Attack are hitting for ~50 each per tick, not to be forgotten, as it all adds up. That's ~4-5 stacks at any given time, 800-1K damage per second if not cleansed.
I found that Infusion of Shadow works better than Shadow protector if you have no init regen, such as Inf. Signet. The healing from Omnom pie should help alleviate the loss of Shadow protector healing. Shadow Embrace is too good not to grab.
If you run Mug and Infiltrator's Signet, you can CnD when close, Sneak Attack, then Shadow Strike away. At that point, use Inf Signet to close the gap again, CnD, Sneak Attack, and then Shadow Strike away again. You can then Mug and do it again.
That adds up to some pretty good damage. It's not as pressuring as a pure glass build, but you have ~3K toughness for the longer fights, and a lot of power, crit, and crit damage to still put some hurt out.
