The various paladin forums have been discussing a few posts by Blizzard on the Alpha forums. Joanadark has a good rundown at Tankspot.
I do not have confidence that Blizzard will be able to fix the paladin class. So far, they have demonstrated an utter lack of a vision for what the paladin class should be. And they show no sign of coming up with a plan anytime soon.
The old vision of the paladin class shattered upon the rocks of raiding. Ever since then, Blizzard has been frantically running around slapping band-aid fixes on each of the paladin specs, hoping to get them--and for the majority of the game, only one of them--at least somewhat raid-viable.
The only saving grace for the paladin class, the only reason we are consistently taken to raids, is because our Blessings are overpowered. Salvation > All.
Think about this:
Even with the upcoming changes to spell and melee statistics, there is not a single statistic which is desired by all three Paladin specs.
Strength - Holy and Prot don't want
Intellect - Prot and Ret don't want
Stamina - Holy and Ret don't want
Crit - Prot doesn't want
Hit - Holy doesn't want
Spell Power - Ret doesn't want
Attack Power - Holy and Prot don't want
Defensive Stats - Holy and Ret don't want
Maybe it's just me, but that seems crazy to me. There should be at least one stat in common to all three specs.
Take a look at the base 0/0/0 paladin. What can she do? She's missing the essential tools for melee dps (SoC, CS). She's missing the defining talent for healing in Illumination. She's missing Holy Shield, the vital talent for tanking.
I think Blizzard needs to start from scratch. Stop with the band-aid fixes. Stop swapping talents around madly. Wipe the slate clean. Come up with a vision for the base paladin and then expand on that vision with the talent trees.
I don't think this will happen in Wrath. I think, just as in TBC, we will get more and more slap-dash patches until one or two individual specs finally become viable, eternally relying on the crutch that is our Blessings.
What is a paladin? I don't know anymore. And so far, Blizzard has shown that they do not know either.
