Looks like you are going for the 40/0/21 Shockadin. It performs well enough in PvP I suppose. Certainly, with the amount of health you have, you better not draw any aggro in an instance or you'll be squashed in short order.
Considering your choices in Ret, it's obvious you are concentrating on spell damage...the lack of Seal of Command and weapon crit bonus makes that pretty clear. Bear in mind again that this build is really only suited for PvP, as Pursuit of Justice is (as an example of some of your Ret talent choices) only useful on a Battle Ground or in the Arena. PvP is a totally different animal than PvE.
Myself, I've been impressed with how my
Paladin has been doing both at main healing 5 mans, and performing on the daily quests. The spell damage makes a difference. So while I might not be enamored of a shockadin, I certainly appreciate the value of Paladin spell damage builds.
