It look promising. 15% more armor and 8% more dmg means more absorb. But still give paladins like 20% more hp and maybe a little more absorb from Bulwark of Order gold trait. Or something that gives us possibility to have shield of righteous up time more.
And about retri... it needs "rework". Blade of wrath and divine purpose should be baseline - those two talents are the only interesting thing that can happen in rotation. Plus blade of justice shouldn't be replaced with divine hammer. Blade of justice is just too cool spell to miss it.
