1. Meta should be relentless earthsiege diamond (agility+crit) and use nightmare tear in a blue socket to activate it.
2. Use agility triumph emblem ring, Dextrous brightstone ring IIRC
3. Use frost emblem leather waist, much much better (you arwe way above hit cap anyways, all you need is 164)
4. Regem arp to get to 53% arpen if you plan on keeping NES. This will softcap your arp.
5. Only buy herkuml if you dont raid ICC10 or fury is your offspec
6. Always use str+crit or str+hit(if needed) in yellow sockets unless its a 3 socket item than gem pure str or Arp.
Also 5 points in Unbridled Wrath is pretty extreme and mostly not needed, I would leave it up to you to decide.
