- Without looking into too much detail you have your gemming and reforging done incorrectly as highlighted:
In both your legs and belt you have haste/stam gems where you COULD have haste/hit gems. With this extra hit you could reforge out of hit other places on your gear (gloves look juicy for some mastery).
You currently have 18057 haste (42.49%) but it would be a dps gain to switch ~1000 of that into mastery via gems or reforges.
You have 8.53% Expertise and only need 7.50%. It looks like you put your character into some reforge addon that aimed at the 2550 mark (hit cap for humans NOT using a sword/mace) but since you're using a sword you can afford to drop that 1% expertise, most likely by dropping some number of exp/haste or exp/mast gems into str/haste or str/mast, respectively.
- You should change around your glyphs. How I set my glyphs up for SoO is using Glyph of TV every fight, with a mixture of glyph of mass Exo, Glyph of double jeopardy, and glyph of inquisition for the other two spots.
I would guess it would be worthwhile to reforge your cloak from crit->exp and lose even more exp gems out for str gems.
I don't use CLC ret but I can tell you 100% that SW is far superior to DP on single target fights and for like 12/14 of the fights in SoO.
