Disclaimers: I am posting this on mmo champ to get opinions before I post on the official forum. I want to make this shorter without getting rid of alot of the "facts". That being said, I do not have a great understanding of most classes self heals, so feel free to correct me. Also, I am well aware that the info here is partyl based off stuff that was just datamined in an early edition of a patch that is months away, so I am not claiming the sky is falling, just making assumptions based on that info.
I used to find it funny that in wotlk, ret was unable to self heal overly well, however we could still do it better then some classes. With the change to 20 second cd on WOG, our so so self heals have gone down even more, but dont believe me just saying that, here are the numbers (and yes, I am aware that this change was made becuase of prot, doesnt mean it doesnt affect ret). Now these abilities have varying amount of dps loss, I will also state all assumptions.
Ret: 1.12k hps
Lock: 2.4k hps
DK: .75k hps to 2.43k hps
Rogue: .8 - 1.6k hps
Warrior .24 - 1.8k hps (I think) no dps loss
Spriest: .48 - .96k hps no dps loss
Feral: .8k hps no dps loss
Enh: .6k hps
Ele, hunters, boomkins and mages have 0 effective self healing. Granted that ele/boomkins could cast spells on themselves, but then they become a quckly ooming healer, not a dps
So what are my conclusions? Well, personally I find it stupid that anyone besides the 4 healing classes can do any amount of healing, self or otherwise. Ignoring that, the numbers above are (at least I'm fairly sure they are) lower bounds on self heals, with the exception of ret which is an absolute upper bound. I find it interesting that (excuse the rp) demon worshipers, the lich kings champions, thieves, and gladiators can heal for more then the warriors of the Holy Light. I also dislike that with the exception of hunters and mages, all healing hybrids do less self healing then pures and tank hybrids. Does the hybrid tax apply to heals as well? Why do 2 classes that are associated with nature do 0 self healing?
Anyway, what I was really hoping to get out of this is this: paladins are a support class with minimal support. At the moment we supply hand of freedom, and a stun. We cant heal others very effectively in pvp because of the low up time on most targets, and the healing we do tends to have a very large impact on our damage done. Hell, repentence is the shortest duartion cc in the game, and its also the only one you have to put talent points into to get (I always found that funny). I dont see ret's getting snares, a charge, or an MS any time soon, so some more support would be really nice. Maybe lower hand of sac's cd down to something where it can be used more then once every 2 mins. Give hand of freedom some dispell prtection maybe. What I would kill for is the ability to clense magic again. I'm not really expecting any of this, but since I know blizz doesnt want ret to be as offensive minded as any other melee, I ask that we be given more tools to do our defensive job with.

Reasoning/calculations (feel free to skip if you believe me)
Ret: Lets say we use a 3 holy power wog on cooldown. My WoG in my crappy ret gear (half heroic blues, half 359 epics) heal for 4500 per charge unbuffed, so I'm going to round this up for the sake of arguement and say it heals for 5k per HP in better gear buffed. This gives 15k heals over 20 seconds, which is 750hps. Add in sacred shield, which is 22k absorbs every 60 seconds, and you get an additional 366 hps.
DK: Death Pact 2 min cd, AMS every 45 seconds. Assuming 120k health death pact will heal for 30k every 2 mins, 250 hps; AMS will double that effect (and im counting this since every class except for warriors has a reasonable amount of spell damage) for 500 hps. Now death strike is a weird thing, it can be used up to (havent played my dk since early wotlk, so excuse me if this is wrong) twice every 10 seconds, giving 1.68 hps. So death strike usage means that a dk's self heals will vary from .75k hps to 2.43k hps
Rogue: Recup, between 2-4% of health every 3 seconds, assume 120k health again, so 2.4-4.8k health every 3 seconds, or .8 - 1.6k hps
Lock: I really cant get a good understanding of how much self heals they get, because alot of it is based on procs. Spamming drain life appears to do 2% of health every second, So for simplicitie sake, going to just leave it at that, since most other increases in self healing are based being affliction. so 2% per second gives a nice flat 2.4k hps
Warrior: First, i assume 2/2 field dressing here. Enraged regen, gives 240 hps. Second wind can give between 0 and 720 hps. Blood craze gives between 0 and 864 hps. Add em up, and you get 240-1800 hps with a reasonable number being about 1k.
Spriest: just using vamp embrace, 6% of damage done heals. I dont really know what a reasonable pvp dps would be so Im just going to half what i think a reasonable pve dps would be, and thats 16k dps. giving us .48 - .96k hps
Feral: Leader of ther pack: 4% of total health every 6 seconds. .8 k hps.
Enh: I am really not sure how much wolves heal for, so going to leave that out. I'm also not sure on maelstrom wep, so since im probably going to get this wrong, going to assume its up every 10 seconds, and you can use you effective heal every time its up (Healing wave heals for what, 6000 as enh???) giving my very innacurate guess at shaman self healing to be 600 hps
