The announced changes seem to be prot-pally related, for the most part (source).

• Blessing of Kings – this spell is now a base ability trainable by all paladins.

Blessing of Kings being a baseline talent is AWESOME. This is something the pally community has been raving about for ages.

• 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.

Exorcism being used in my normal rotation? Currently, Exorcism only works on the undead. I think I’ll need more mana for that!

• 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 causing Avengers Shield AND Shield of the Righteous to cause a 3s silence? That sounds OP to me, even if it is prot pally only.  My guess is that the CD on SotR will be increased a bit.

• Ardent Defender, Improved Hammer of Justice, One-Handed Weapon Specialization and more have had their ranks reduced.

Very nice change. My 5/58/8 (or the most popular 5/60/6) will have at least 9 talent points freed up (giving back 5 from kings and 4/5 from the 2H weapon specialization). Will the tree be given MORE bloat or will prot pally’s be able dabble more in the ret tree for some added damage (and therefore threat)?

• 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.

So now there is a 100% chance to keep Divine Plea going every time I hit someone/something with my shield? Why do prot pally’s need spiritual attunement anymore?!

• 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 drops the CD of Hammer of Justice to 30seconds in itself, but there is another talent in the prot tree that further reduces the HoJ cooldown by 30s (for 3 talent points – but, with 3.1, will be only 1 talent point). This effectively gives pallys a 10second interrupt/stun. This seems overpowered (especially in PvP) to me and leaves me wondering what kind of nerfs HoJ will receive.

The only other change mentioned regarding pally’s is a huge nerf to Divine Plea. It’s impact on healing is being increase from a 20% reduction to 50%. The duration and cooldown remain the same however (source).

• Since paladins rely less on Spirit as a mana-regeneration stat, we have to address them in other ways. We don’t want to change Illumination or Replenishment. However, we are going to increase the healing penalty on Divine Plea from 20% to 50%. Divine Plea was originally intended to help Protection and Retribution paladins stay full on mana. It should be a decision for Holy paladins, not something that is automatically used every cooldown.
• In addition, we are also changing the way Spiritual Attunement works. In situations with a large amount of outgoing raid damage, as well as in PvP, this passive ability was responsible for more mana regeneration than we would like. We want to keep the necessary benefit it grants to tanking Protection paladins, while making it less powerful for Holy paladins in PvP or raid encounters with a lot of group damage.
