At a glance I can see a number of issues with your armory
1) Change the windsong enchant on your offhand to living steel weapon chain to decrease disarm effects by 50%. The additional windsong enchant is not worth it. Dancing steel would be the better enchant for your main hand as well but since it's expensive as balls, this is splitting hairs. (I can't afford it either.)
2) Your hit is too low at 2.40%. It needs to be at 3%.
3) +180 agility is the preferred enchant for your bracers. Mastery is a humble substitute only if you can't afford the agility one.
4) Your choice in gems is...terrible. I'll elaborate:
5) Because of your gemming issues, your PvP power is incredibly underwhelming for your iLvl.
You can take a look at
my armory for reference. You'll notice right away I'm no elitist player; I am the dreaded "casual"...but take a gander at my PvP power and resilience.
I'm a whopping 7.37% higher than you in PvP power despite your gear advantage. And what did I trade for that? A measly 3.5% resilience in comparison.
~8% additional damage is serious, serious business; 3.5% personal damage reduction is not. Keep in mind this 8% does not factor in the attack power you'll be getting from agility, so your true damage gains will likely be even higher.
Re-gem. You will thank me.
6) Despite all the bitching I just did, I'll tell you what resilience DOES beat: stamina.
Switch your chest enchant to
Super Resilience. Resilience translates into more "effective health" than raw stamina does to actual health. In this case 200 resilience wins over 300 stam.
-----------------------
Your talents are fine. But having looked at your glyphs...
Glyph of Stealth should be replaced with
Glyph of Blind since you did not spec into
Dirty Tricks. Without it, your Blind is essentially useless. That's a BIG no-no.
That's all I got from a quick glance at 4AM. I'm going to bed.
