Eyonix posted the list of changes for the remaining classes. Here are my thoughts on the paladin changes.
Blessing of Kings – this spell is now a base ability trainable by all paladins.
What a long road we've been on to get to this point. Ah well, no more whining about Kings. I wonder what the new Tier 1 talent talent will be.
Exorcism – this spell now causes damage to all types of enemy targets. However, it always critical strikes undead or demon targets. This change should make sure paladin damage doesn’t drop when going from Naxxramas to later tiers of content.
Very interesting. A nice buff for Holy soloing, and normalizes Retribution damage across all enemy types. The only concern I have is that this does add to PvP burst, as Exorcism is now usable on players. CS, Judge, DS, Exorcism, CS is now a complete string of attacks with no breaks in between.
Shield of the Templar now causes your Avenger’s Shield and Shield of the Righteousness to silence targets for 3 sec. The old damage bonus of this talent has been folded into Holy Shield, Avenger’s Shield, and Shield of the Righteousness.
Shield of the Templar becomes a PvP talent mainly. Frees up some points for PvE builds. A 3 second silence every 6 seconds on the highest damage ability sounds a little bit crazy though. I expect this to get nerfed once it's on the PTR.
Ardent Defender, Improved Hammer of Justice, One-Handed Weapon Specialization and more have had their ranks reduced.
Thinning out the Protection tree heavily. The real question is whether these talents will provide the same effect for fewer talent points, or will simply provide a smaller effect. I can almost guarantee you that Imp Hammer of Justice will be reduced to -10 seconds for 1 talent point and become the 11-point Protection talent. It's a solid nerf to Ret PvP, and Ghostcrawler will probably be happy to see us shut up about missing that 11-pointer.
Now, what will happen with Ardent Defender and One-Handed Weapon Specialization is more nebulous. Either way, Protection just got a lot more points to put in the secondary trees.
Guarded by the Light – no longer reduces the mana cost of shield spells, but now has a 50/100% chance to refresh Divine Plea duration.
I'm going to take a wild guess and say that Shield of Righteousness is the spell which will refresh Divine Plea. It's actually pretty elegant, creating a mana-return mechanic around ShR that the Protection paladin should be able to keep up throughout the fight.
Judgements of the Just – now also reduces the cooldown of Hammer of Justice by 10/20 seconds and increases the duration of the Seal of Justice stun effect by 0.5/1 second.
This is the reason I predict Imp HoJ is the 11-pointer. This talent would mean that Protection still gets 30s HoJ, but Retribution does not.
I'm not entirely sure why Protection PvP is being pushed, but I, for one, welcome our new Protection overlords.
