Currently ret does not fit the description blizzard has for paladins at all.
For a New player this is how paladins are described by blizzard. http://us.battle.net/wow/en/game/class/paladin
Currently paladins are so far from there role that the class has become more of a joke than anything. Currently we are all about a 30 second burst window and after that the sustain damage is less than a warriors healing from second wind. With weak heals and a lack of abilitys to protect your team, the class needs evaluation to say the least.
Our Hand of Blank's are all dispellable and have not been given any evolution or complexity since they where made.
So these are the changes I propose
[Hand of Salvation] is not used at all outside of raiding, when you cast Hand of Salvation on the target they become uncritable. This would add more diversity to a paladins arsinal of ways to support his team in pvp.
[Hand of Freedom] Hand of freedom would reduce the duration of stun by 50%, if you cast it twice the stun is removed. This would be a smart thing to do because it adds another aspect to freedom where the paladin has to think ok do I want to use freedom to get out of this slow or to reduce the incoming stun.
[Hand of Sacrifice] I have a few ideas for this spell but blizzard on 5.2 ptr made it dispell the affected target, however this is not as good as shadowpriest dispell's but it's nice to have 1/100th of my old dispell back...
[Holy avenger] I would make it a 30 second cooldown that Makes your next 2-3 holypower generating moves give you 3 holypower and also increase the holy dmg of your next tv by 45-65%. You would have to Slightly buff all of our damage moves to compensate for the change, as we would lose alot of burst.
Instead of this being another long 2 min burst cd, I would turn it into more of a tigers fury rotational burst. Ret has a 5 minute cd pet and a 3 minute cooldown on wings it does not need a 3rd.
All that does is design us around being a all out or nothing spec which is wrong for the paladin role. For no reason should I out damage true Dps classes for 30 seconds and than be out dpsed by a pet once my cooldowns are gone.
[Crusader strike] currently this move hits for 8-11k nonecrit depending on the targets resilence and 20-22k crit. I would remove the cooldown from this ability or make it a 1s cd. I think having cs as that move you spam like sinsiter strike or mangle makes more sense than any in buffing there sustain because of the dead time in the rotation, you might have to reduce a % of wep dmg slightly if this is done.
[Long arm of the law] I would make it give you a speed increase if the target is more than 10 ft away and a 50% slow to the target if they are less than 10 feet away.
[Divine Protection] Should be castable while stunned at the very least. We Lack any serious midigation considering 75% of the arena comps and all Rbg comps can remove my only large midigation in .5-1.5 seconds
[Repentance] Repentance has always been a ret move and we never had to choose between it or a reliable stun. So I propose it remain Ret only on a 30-40s cd.
Also Each holy power should also increase it's cast speed by 1/3, and 3/3 holypower is instant cast.
[Emancipate] this is more of a question in regardess to Emancipate. Why did you Change our self dispell from being a remove all impairing affects to removing one? This really hurts considering we are the only melee without a massive way out of CC, Berserker rage, Sham rage, tremer totem, lichbourne, icebound, Ams, or passively being immune to poly affects like feral.The new emancipate is terrible it cost 1/6th of my entire mana pool and you almost always have to cast it multipule times to reach your desired affect.
One thing that is important when balancing paladins is spreading out the buffs, you cant massivly buff Flash of light for example and than leave wog weak. You should Add A medium volume of increases to both no one wants to go back to a season where a Ret paladin can top someone off in one cast but instead a class that can heal someone up and protect them with a combination of spells. One last for note blizzard before you procced with fixing this class you should google the world balance.
