Is XX Dodge/Parry better than YY <stat>.
Was replying to a thread on the WoW tanking forums. And got me thinking. Maybe some of the number crunchers can figure this out better than I, and tell me if I'm way off base here.
Was seeing many people ask what gems to place in their gear. How much Dodge or Parry is too much. At what point does it become useless to get more Dodge rating. Etc, etc.
This is just a copy/paste of what I posted on the WoW forums.
I'm not sure if the math is even close to right on this - but at least this is how I see it in my head...
Now in the game we have al these ratings that are effected by diminshing returns. They diminish in effectiveness the higher your rating is. Even though Armor does not have a "rating" associtated with it, if you think of it that way, it becomes easier to see the relationship between it and Dodge or Parry.
At level 70, 10,000 armor (rating) reduces incoming physical damage by 48.644%. Increase your armor (rating) two fold - to 20,000 only yields a 65.45% physical damage reduction, due to diminishing returns. Your overall "time to live" (as some like to call it) has actually doubled, as it will take twice as many hits to kill you.
I am using this line of thinking when I compare Dodge/Parry to Armor/Stamina. If I increase my Dodge rating from 100 to 200, that would be the same gain as going from 1000 Armor to 2000 armor - regardless of what the percentages on my character sheet reflect.
