Macros and Useful Addons.

Macros. - Remove the quotation marks.
Aura Macro - Always remember to switch between your auras to the times you need it, if you've got resistance aura against a warr/rogue combo, you're an idiot.

"/cancelaura

/castsequence devotion aura, resistance aura"

Burst Macro - THIS IS ESSENTIAL Always remember to use your burst macro when you need that extra damage, mostly used to take down healers as well. Always click on Divine Plea after you use the macro then wait till Sacred Duty pops and get dem 70k SoTRs on 5k resils.

/cast Inquisition

/use <Trinket>

/cast Divine Plea

/cast Avenging Wrath"

CS/Judgement HoTR/Judgement Macro - This helps relegate your cooldowns on judgement and your two main holy power generators, it's also useful to keep your button space lower.

"#showtooltip

/castsequence reset=2 crusader strike, judgement, crusader strike"

"#showtooltip

/castsequence reset=2 hammer of the righteous, judgement, hammer of the righteous"

Mitagation Macro - THIS IS ESSENTIAL Use this before your bubble to possibly save your life by reducing drastic amounts of damage and healing you back up to 15% if you take a hit that can kill you, using WoG strategically after Ardent Defender procs can turn an arena battle around by healing you back up to 70%. 

"#showtooltip

/cast [mod:ctrl] guardian of ancient kings

/castsequence reset=30 divine protection, guardian of ancient kings, ardent defender"

Focus WoG - Focus Flash of Light - Focus Hand of Sacrifice - you should always help out your partner in a damage/damage comp, if he/she needs the extra heal throw them a spare WoG or flash of light. You can use hand of sacrifice strategically to break out of stuns/snares/bonds that can be broken by damage. 

"#showtooltip

/cast [mod:ctrl] holy radiance

/cast [@focus, mod:shift, nodead] word of glory; word of glory"

"#showtooltip

/cast [mod:ctrl] holy light

/cast [@focus, mod:shift, nodead] flash of light; flash of light"

"#showtooltip hand of sacrifice

/cast [help] hand of sacrifice; [target=focus, exists, nodead] hand of sacrifice"

Additional Macro FOR PROS ONLY USE WITH EXTREME CAUTION - Use this all the time since you're a pro by following my guide you'll obviously need to constantly laugh at your enemy and make them feel pathetic.

Addons.

There are no essential addons for Prot Paladins specifically but personally I use the essential PvP addons and the useful ones for pvp in general.

 

Bartender UI

Cooldown Count

Gladius

IceHUD

Killshot

Quartz

TidyPlates.

These are mostly aesthetic addons to make PvPing easier though I still recommend them. 

Rotation.

Your main rotation is Crusader Strike > Judgement > Avengers shield > Holy Wrath > Repeat
-Always use Avengers Shield when Grand Crusader pops
-Always start with Avengers Shield if the target is far away
-Do not forget that you can use your Avengers Shield to interrupt spell casting and silence and enemy
Use SoTR when you have 3 holy power and if you reach 70-80% HP use word of glory, always keep in mind of your WoG CD because it could reverse your arena if planned correctly.

Now this is the part that most prot paladins in PvP forget, a magical little spell called 'HOLY SHIELD' This increases the amount you block by 20% for 10 seconds, and with that secondary mastery you've accumulated you should always use this during times of heavy damage eg. when somebody pops their cooldowns. 

Use Hand of Freedom wisely as you still have a 25 second cooldown on it, you can become unstoppable by using it correctly with your pvp trink/racial eg. frost mage uses deep freeze > use your trinket > frost mage uses frost nova and/or wind breath > pop hand of freedom to get close, silence with avengers shield, use hammer of justice before or after the mage blinks away > pop burst and down the mage.

Cleanse is extremely helpful in times of heavy damage as well so use that wisely, keep an eye on your mana whilst using this spell though.

Always help out your partner by throwing a few heals their way or even popping hand of protection on them when they need it, remember that most of the time you can only use hand of protection once in a 2's match so use that only when you know you need to. ALSO REMEMBER THIS DOES NOT PREVENT MAGICAL DAMAGE. 
Helping out your partner is also covered more in the macros section. 

Gems, Enchants, and Stat Priorities

Gems.
Meta: Reverberating Shadow Spirit Diamond - +53 Str +3% Crit Effect.
Red: Bold Inferno Ruby/Bold Queens Garnet - +40 Str / +50 Str
Yellow: Mystic Amberjewel/Mystic Lightstone - +40 Resil/ +50 Resil
Blue: This choice is down to you, if you want to go for some extra stamina then put a couple solids in there, or you could get some str + additional stat in there.

Enchants.
Head: Arcanum of Vicious Strength
Shoulder: Greater Inscription of Vicious Strength
Cloak: +50 Critical Strike Rating
Chest: +40 Resilience / +75 Stamina / +20 All Stats
Bracer: +50 Critical Strike Rating
Glove: +50 Strength
Belt: Ebon Steel Belt Buckle
Leg: +190 Attack Power +55 Critical Strike Rating
Boot: +30 Stamina and a movement speed increase / +50 Mastery
1H Sword: Pyrium Weapon Chain
Shield: +50 Mastery

Stat Priorities.
Obviously your main stat is strength followed by 5% hit and 20 expertise (10 expertise from gear and the last 10 is provided by your glyph of seal of truth and the use of seal of truth) then critical strike rating.
So: Str > 5% Hit 20 Expertise > Crit > Mastery > Haste.
HASTE IS NOT NEEDED DO NOT STACK IT YOU NOOBS. 

Talent choices and Glyphs

Going to keep this short and sweet. Reasons:
1 Point in Divinity and Toughness - This provides a good dump for your 2 extra talent points as it gives a small yet sufficient extra to your armor and a surprisingly big increase to your heals. I did not choose Hallowed Ground as I only use my consecration in pvp to fish out stealthers, hell I hardly use that spell due to the comp I play anyways. If you feel like the extra point in toughness is not needed, feel free to put it in divinity. I get 80k heals just from putting 1 in so you should probably get more.

Eye for an Eye instead of Improved Judgement. - I tested with both and I found that having some extra damage against a caster proved to be more useful that having a longer judgement, especially with Avenger's Shield handy.

Glpyhs.
Prime:  Glpyh of Seal of Truth; Glyph of Shield of Righteousness; Glyph of Word of Glory
Major: Glyph of Dazing Shield; Glpyh of Focused Shield; Glyph of Rebuke
Minor: Glyph of Blessing of Kings; Glpyh of Blessing of Might; Glyph of Truth

Introduction to Paraxynd and prot pvp.

Full cataclysmic prot paladin on WoW Freakz. I play casual arenas since this spec isn't catered for hardcore. If you want to play hardcore arenas I recommend holy pally for this patch. In this spec you'll be getting high crits, and a constant stream of high hits only during your burst uptime which will be explained later on. This guide is only for dominating random battlegrounds and destroying arenas till about 1900 or so. Please feel free to make comments and suggestions to this guide as i'll be reviewing and changing it accordingly. This spec choice is a huge amount of fun for being near unkillable at times and bursting down heavy dps even though it isn't considered a viable pvp spec in cataclysm.
