None So Far
As stated previously, there haven't been many Paladin changes thus far in the Cataclysm testing process. However here is a brief run-down of the changes which have come to light so far (compiled by Alpha Tester Valoriel)
The Paladin talent trees have not yet been updated (not counting today's patch, hopefully this is it!)
-Blessing of King and Mark of the wild are now the same, granting 5% to all stats except spirit and some magical resistance. The 3 resistance Aura have been merged into a single aura Flash of Light heal significantly more but also cost significantly more Beacon of Light no longer affect any spell other than Holy Light. A new heal is available: Divine Light. It heal for a large amount of hitpoint and has a casting time of 3.5s. Think of it as a paladin greater heal. The spell isnt trainable yet. Blessing of Wisdom has been folded into Blessing of Might. Blessing of Sanctuary has been replaced by a placeholder talend named Sanctuary, granting the effects of the now defunct Blessing of Sanctuary to the paladin as a passive permanent effect. Crusader Strike is now available at level 1 and it really make a world of difference. Crusader Strike is currently replaced by Improved Crusader Strike (Increase the damage done by Crusader Strike by 10%) in the Retribution tree but it is a PLACEHOLDER. Shield of the Righteous now scale of attack power as block value has been removed. Protection paladin now get more chance to block through their mastery stat instead of the announced Block Value. Consecration now deal significantly less damage per tick but last 15 seconds. The cooldown is still of 8 seconds but please note that you can only have one consecration effect up at any time. I will post a description of Healing Hands when i can log back in. The spell exist but we cannot reach the proper level yet. From memory it is an instant spell, has a 10s cooldown and heal everything in a 10 yard radius around the paladin (but i may remember it wrong). Blinding shield is not yet available.
A new patch is download as I write this, which will hopefully see more Paladin changes. I'll formalise this list of changes as and when we see something new.
