Here are the numbers I'm working with at the moment. I would really appreciate anyone that can help me to fix anything that I might have gotten wrong in my calculations.

Note One: I assume that Rage of Halone is not a flat -10% damage reduction based on the fact that is Strength and not physical damage reduction outright.

Note Two: I was using another persons numbers from Reddit for the Rage of Halone damage reduction, so I'm not sure how accurate those are. I haven't played my Paladin in ages and thought it would be quicker to get input from others who actively play theirs.

Note Three: This is assuming the perfect scenario where Both Paladin and Dark Knight get a Parry and have their respective damage reduction abilities applied to the mob on a 10,000 damage tank buster.

Note Four: Again this is for Physical only, as it is already clear that Paladins are behind Dark Knight when it comes to Magic Damage.
