Using [Persistent Earthshatter Diamond] as your Meta gem is not optimal. This is for 2 reasons, #1 being that it requires 3 blue gems (which are by far the weakest DPS gems), and for the fact that something like the Relentless Earthsiege Diamond, which grant 21 agility and 3% increased crit dmg is much much better. You should immediately replace that gem and re-gem accordingly.
Your spec and Glyphs look fine for the most part however I'd drop the Glyph of Bloodthirst for the Heroic Strike one. The Bloodthirst Glyph isn't a DPS increase at all.
You're missing out on crucial gem bonuses as well. A yellow socket in your helmet grants 8 strength, but you opted to put a 20str gem in it instead. If you had put a 10str/10crit gem in it, you would have gotten 18str and 10 crit vs 20 strength. Generally for yellow sockets, if the bonus is at least 4 str, you should put an Inscribed Ametrine in it (10str/10crit). Switching to the Relentless Meta like I previously mentioned allows you to only have one blue gem which will be a Nightmare Tear (+10 to all stats), put this in your best blue bonus socket.
Other than that I can't really think of much else, try to get your expertise up to 26 at least, lose some hit, get some more ArP, get your 4p tier 9 set. Generic fury advice.
