There are a few things that will help out somewhat. First, Drop all your STR/STAM gems and you STR/Haste gems. Also change out your meta the the 21agi and 3% crit damange. Only gem for solid STR unless your socket bonus is more than 8Str. Get Berserking on your weapon. That will help some. Also replace the Needle Encrusted Scorpion ASAP! I see that you have the Libram and the Belt from frost emblems, However no t10? If i were you i would not waste emblems on those items untill you have at the very least a 2set bonus on your t10. If you are not wanting to get the set bonus, then you can spend 60 emblems on the Herkuml War Totem. That is the best trinket you van get for ret outside of ICC 10.25 If you have the gold you can get a Darkmoon Card:Greatness get the str one. that is going to be solid upgrade for either of your trinkets. You may consider respecing as well. The 2 points you have in Vindication are pretty much useless, use those 2 points and put them in finishing up Divine Intellect and then grab aura mastery. As far as your rotation, you should change a little. Where your gear is at you should be using something more along the lines of, CS > HoW > Judge > Conc > DS > Exo That is all the basic stuff. Hope this helps some.
