Paladin Tank Armor Buff Needed

I have been playing a paladin tank since TBC. I love the class paladin and have a paladin as always been my main. Currently Blizzard NEEDS to buff paladin tanks ASAP. I have never cared about being a “Meta” class. I don’t care to push into crazy end game content, however with 9.1 being release paladin tanks require a major buff. They are currently the squishiest tank and I think blizzard either needs to make Shield of the Righteous stack or increase the armor value more. The other resolution is give protection paladins a base armor increase like warriors have.
