1) 9/10 great gear
2) Build looks interesting. I would change the run on SH to vengeful spirit for a nice dmg pop with no animation. Chances are you are harvesting more souls before that time expires anyways.
3) Vile ward can use an upgrade to one with life% or vit. Your life is what is slightly lacking atm running only 46k with an amethyst in your helm. Nice amount of AR though... maybe even too high. The key is to get a good balance of AR/armour/life. To me it seems like you could sacrifice some AR for a lot more life to make it so AR isn't hitting diminishing returns.
4) Nice cc pox.
