So the other day I thought I'd try queuing as tank (I'm only geared for DPS) to take advantage of the satchel of exotic goods reward. I have 0 dodge, 0 parry and hardly any mastery on my DPS gear. I ended up flying through the dungeon and even soloed the first boss of scholomance (our whole group failed). As a DK, I'm pretty happy with the fact that blood can do so much damage and have great surv in pvp and pve. I know it's just a heroic and not a proper raid, but still. It's nice to be able to que as tank just for the lulz.
