Can't Wait :DFollow

Thats right, I am finally coming back to World of Warcraft after a year and a half of not playing, and the first thing I wanted to do is start a fresh Paladin in my friend's server. However, a lot has changed in a year and a half, and I wanted to get serious with this new Paladin enough to be worthy of being in my friend's guild (who are already raiding ICC) eventually. I want to go with a full Retribution specc for both PvP and PvE by using that new thing called Dual Speccing, and here are two of the builds I came up with:

PvE:

I plan to use this build with Blessing of Might, as I wont have to worry much about taking damage in raiding, so the extra HP from kings wont be needed. I also plan to use Judgement of Wisdom to increase the "lifespan" of my mana during a boss battle and such. Finally, Ill be using Seal of Command on mobs and Seal of Corruption on bosses. So, overrall, in this build I try to maximize damage as a priority over survivability, which is not too necessary when in a group or raid. Also, this would be my leveling build.

PvP:

With this build Ive tried get as much damage as I could while also increasing survivability to a certain extent and getting talents that serve the sole purpose of support when in BG's or arenas. Here I plan on using Blessing of Kings, Judgement of Light and Seal of Command.

So, feel free to help me improve both the builds and the gameplay involved with each one. Here, I have only made up builds based on research but I also want the opinion of those who are familiar with all the new content. Do hurry up though, as I start playing again on 5 days! yay! :D
