So why play anything other then paladin?
-Everyone can now block magic damage, paladins have a shield so they can do it better. -Paladins can now aoe tank like bosses with more mitigation.
-Warriors can't self heal anymore paladins have clemency so why bother.
-Same dps now pretty much across all the tanks slight edge with paladins.
-No one asked for blackest night on DRK I do not see how this helps scholars, and astrologians did it fine.
-As far as i see enmity generation is nearly the same too so why bother.
-Overall highest potency spreadsheet on paladins.
-Oh year blocking and parrying are nolonger direction so year paladins are just as good at aoe pulling as DRKs (No more DA+DD)
So basically outside of selfish a desire to play to your flavor, your gonna be gimping your group by playing any tank that's not a paladin.
For shame square in your shameless aim for balance you've killed variety and any reason to play other tanks in a group setting.
