Skater, you are currently below expertise cap which considering you are not glyphed for it, is strange. Expertise after hit is your most valuable stat and as such should be kept at cap whenever possible and certainly is more important than your avenging wrath glyph.
You are using some poor quality gems are using the wrong meta (the correct being the agi+crit damage paired with a nightmare tear) and are in generally poorly itemized gear considering how far into 3.2 we are I would expect you to be mostly farmed through 25m ulduar content. 7/10 Fix your gems, fix your itemization, and youre doing fine.
**edit** deducting .5 for using icewalker while above hit cap. Go get 32 ap. 6.5/10 Better yet before you even go get the enchant how about getting either the plate or leather crafted boots since both are better.
A couple things of note
1) I know FotFF is "mo bettah" I just have never seen it drop let alone won the roll on it
2) I know im below my expertise cap, this is a recent development and I cannot at this point in time rework anything to change that without suffering a higher dps loss (recent parse from 25m fire fighter showed 1 dodged attack.
Now comment away.
