I don't know about that.
Us pallies are getting Holy Shock on all specs, Sacred Shield lasts for 30 minutes, so we won't have to keep casting, and look at this:
That's nice#
Guardian of Ancient Kings (85)
Summons a guardian that works differently depending on the paladin's spec (it also looks like the winged angel-like creature from WarCraft III's Resurrection spell). 30 seconds duration. 3 minutes cooldown.
*
Holy: Heals nearby wounded targets, preferring the ones with lowest health.
*
Protection: Absorbs a portion of the incoming damage.
*
Retribution: Attacks nearby enemies (like Summon Gargoyle).
Blessing of Might and Blessing of Wisdom are being combined, therefore giving us ret pallies MP5 as a buff also, which will always be helpful in arena.
Our Crusader Strike is also said to become more powerful like the Death Knights Blood Strike becomes Heart Strike.
Basically, the paladins only nerf so far is that Beacon of Light is designed so that it only doubles Flash of Light, rather than all healing. Of course, that is for Holy specced pallies, though.
