Very nice Calamity DH; great all round stats and pieces. I would maybe try to focus on replacing the miscellaneous stats such as STR and INT for some more VIT such as on your Bracers, Ring, or Gloves. Other than that, very good overall.
9/10 (only could use more EHP, your DPS is great)
Lastly, to whoever rates my DH: please note I am in my balanced PVP build with a mix of damage, EHP, and discipline.
