Tanking in ICC - Defense Rating
Currently my guild is just getting into ICC 10 man, we have downed Lord Marrowgar and have been rep farming for a while now. I've heard rumors about being over defense capped for ICC and that being so will help me take less damage and overall help my healers/raid more. Just want to see if this is true.
Here is a link to my armory Paladan I'm currently sitting at 555 defense rating, with 16 defense rating on my cloak and 20 defense rating on my shield. Just wondering if I should change those out and go back down to 540 defense rating or if I should stay where I am and stay over defense capped.
Any scrutiny/helpful comments/criticism about my gear/spec/gems/enchants would be most greatly appreciated and welcomed. Thank you all in advance.
