on one hand you could have low parry that isnt subject to DR, so your parry rating is used to its fullest, where on the other hand you may have tons of parry, making it worth less because of DR
Without that clarification, they are contradictory. If i say:
Con: My house is more likely to catch on fire
Pro: My house won't catch on fire
those
are contradictory if I forget to add "when it's raining" to the second one. Specifying that you're considering very different scenarios is pretty important in that case.
In addition, when discussing diminishing returns, one is usually referring to the entire range of that stat, in which case it's incorrect to say Parry is subject to less DR than dodge. If your pro under "mitigation" had read "
For a character with very low parry and high dodge, Parry rating can give more avoidance than Dodge rating," then we'd be in complete agreement. But as you'll see, that very specific case is also pretty unrealistic.
More to the point, I don't know any tankadin that has low parry. Perhaps if you're in really low-ilvl starter gear after just hitting 70. The ilvl 200+ gear that drops in raids is already overbudgeted on parry, so if you're getting any Naxx gear you're going to have more parry than you want in the first place. I think it's safe to say that for anybody who's got gear appropriate for 25-man raid tanking, parry will see worse diminishing returns than dodge.
This thread gives more of the theorycrafting behind it, but at current gear levels, ideal ratios would be equal parts dodge and defense rating, and a parry rating equal to approximately 1/5 of your dodge rating.
Which means your very specific (very low parry and high dodge) case where Parry is better than Dodge is also unrealistic for anyone who's at the level of tanking heroics or higher. Overall, this means Armsman is a bad "best choice" to be suggesting for the vast majority of tankadins.
