Due to unlucky drops for my righteous shoulders im forced to go for the S1 shoulders think these would be ok for tanking kara in?=( oh and i was wondering about resilience rating not really sure how or if it works in PvE.
Here is a link to my armory http://www.wowarmory.com/character-sheet.xml?r=Bloodscalp&n=Ocaulith
oh and im using FotC not Insignia of the Alliance for tanking. Thanks for any help you guys and throw me.

I'm likely going to grab the S1 shoulders myself. I've got the marks and tokens saved up. The resillience will help make up for the lack of defense, as resillience reduces your chance to be crit same as defense. However your going to need to make up the avoidance elsewhere. If you can do that then you should be golden.
