Too much dodge?

Little question for the pro DK tanks out there. I read that you want to keep your dodge and parry ratings near the same. What's the reason for this, and is it possible to have too much dodge?

Thanks!
I'm not entirely certain on the specifics but I'm almost sure it has to do with dodge and parry sharing a DR and it being more effective to have 13/13 dodge and parry rather than 17/11 dodge and parry.

Dodge and parry are on separate DRs that depend on the ratings. As you get a higher rating, it takes more and more rating to obtain the same 1% dodge/parry. If you have a much higher parry rating than dodge rating, 1 point of parry rating gives you less mitigation than 1 point of dodge rating, so it would be better to reforge out of parry and into dodge. To minimize the DR effect while maximizing mitigation, you want to keep them equal because it minimizes the individual DRs.

You also need to account for agility in your dodge rating DR, since it contributes without showing up as dodge rating. Raid buffed, you're going to want ~300 more parry rating than dodge rating to account for this. Unbuffed, it sort of just depends.

edit: as a note, Swordshattering doesn't affect the DR curve because it doesn't give you any ratings.

Excellent explanation, thank you.
