    Avoidance DR

    Dodge, parry, and miss are subject to diminishing returns. When you determine how much dodge/parry/miss you gain from rating or defense, it must be converted into the diminished amount. The diminished amount is what is added to your dodge/parry/miss chance.

    What are diminishing returns? One definition puts it this way: The principle that further inputs into a system produce ever lower increases in outputs. Basically, you get less avoidance for every point of rating than you got for the last one.
    Some things worth noting:

    - The diminishing returns on dodge, parry, and chance to be missed are independent of each other. Each has its own cap and formula.
    - Avoidance contributed by defense is subject to diminishing returns, as will be shown below
    - Your base (naked) avoidance and avoidance given by talents and racials is NOT subject to diminishing returns, and are not included in the formulas. Just add them on at the end.
    - The cap for miss has been verified for warriors only at this time.

    The total change in an avoidance type (i.e. dodge, parry, or miss) from all sources (rating, defense, agility, etc.) must be calculated together so that the result correctly takes the diminishing returns into account. When considering an item and whether it is an upgrade or not, a total recalculation of each avoidance type using the new item's stats and all stats from other items, buffs, etc. must be performed. To avoid a great deal of tedious calculation and recalculation, an addon like Whitetooth's RatingBuster is highly recommended. RatingBuster will do the complete recalculation for a given item, and display the correct increase or decrease in stats in the item's tooltip. Get RatingBuster: WoWInterface, Curse

    Here's a sampling of rating vs. avoidance (pretty graphs are below in other posts). Expected value is simply the amount of rating divided by the rating per 1% (what you would have gotten in TBC), diminished value is what you will actually get. Rating is the appropriate rating for the avoidance type - that is, dodge rating for dodge chance, parry rating for parry chance, defense rating for miss chance. See post #2 to see how defense+dodge and defense+parry ratings go together to calculate your total dodge and parry chances.
