Gonna work on this over the night, but for now just wanted to share a very helpful addon for having a tighter rotation.

Basically, it highlights a skill based on your priority system, what's on CD, and what proc (art of war). More of a visual aid for a paladin looking to up their dps.

Spec
http://talent.mmo-champion.com/?paladin ... ere3,10952

Base spec, leaves 6 talent points for you to decide between Divine Sacrifice or Aura Mastery.

Rotation/Priority
1. Judgement - Hardest hitter, returns mana, can't go wrong with this as your top priority.
2. DS - DS only pulls ahead of CS with 2pcT10 equipped, as its' effective cooldown drops to 6 seconds, and it hits much harder than CS does.
3. CS - Because of the short CD and ability to proc a seal, you want to keep this on cooldown as much as possible.
4. HoW - This skill only comes into play when a mob is at 20%; it then becomes high priority due to it's extremely high crit rate and fairly short CD.
5. Consecration - Consecration moves near the top of the pile only against multiple (4+) adds.
6. Exorcism - It hits hard, but because of it's somewhat long cooldown (15s) and reliance on spellhit, it isn't great dps. Do not use this on a pull because it will not be instant cast, and will delay entering melee combat.
7. Holy Wrath - Only effective against multiple (6+) demons/undead, you are better off using your free GCD casting DP or a SS on someone. This is as close to a mana dump skill as we have.

Itemization
Get hit to cap, then str is by far the strongest stat. Expertise and crit are nice, but not worth gemming/enchanting for.
Use agi/crit dmg meta, 1 nightmare tear in best blue socket to fill requirements. Gem everything else str with the following exception.
If you have ONE socket in a piece that is yellow with a STR bonus of 4 or higher, you can safely use str/crit or str/hit if under cap.

This is an extremely brief summarization. For more detail please visit the link earlier in the post.
