First off, heres my armory.

Ive noticed since 3.1 dropped, when tanking I've been taking significantly more damage than I did pre 3.1. I tried deep frost and just didnt like the aoe threat. Ive been unholy since 55 so maybe i'm a little biased. I went back to deep unholy which was what I used to MT for my guild with no issues. Now that I'm back to deep unholy, even with glyphed boneshield up, my healer had trouble keeping me up in heroic Nexus. I've talked to warrior and paladin tanks in the guild and they havent noticed anything different. Am I just on crack or has any of the other DK tanks noticed this?
