So while leveling my DRK in sohm al, a healer said something that got my attention, and this was "man drk why are you taking so much damage, did you forget to repair your gear or something."

And it truly did feel like that even though I had no broken pieces. My gear was the highest you can get at that point, the i130 gear that drops from that very dungeon so that couldn't have been it. Yet I'm getting hit in the high 800 ranges (maybe 650-750 with some CDs), and of course even higher when something crits, so in a group of 3 I'm getting hit like 1500-2500 every few seconds depending on the mob or which CDs are active. I have 10050 HP.

Any reason as to why this is happening other than defensive CDs? My PLd doesn't take this much damage, YouTube videos of DRKs don't seem to take as much damage AND they're popping less defensive CDs than I was, some even going into dps stance straight up. I always have tanking stance on unless nothing is focusing on me specifically
