Firstly I would like to say thank you to the whole community here who have helped me immensely in gearing my character and perfecting my tanking style etc.
Secondly, I was wondering if anyone could help me out. I was running naxx 25 the other day and was taking hateful strikes along with a dk, but, time and time again I would end up tanking the floor. Here's a link to my armoury; The World of Warcraft Armory
I just want to make sure that I'm not crazy to think I could take hatefuls. Just for reference, I think I had about 35k hp buffed.
IMO you're fine for all of Naxx 25 including Patch - the problem, as you may suspect, is with your healers I'm afraid.
