DKs bring battle rez and a 40 percent spell damage reduction bubble every 3 minutes. It's far from Pally levels of utility (they are king of all tanks by far) but it's not nothing.The best tank with the most raid utility by far is paladin. DK is very forgiving, but they bring 0 utility in the form of raid cooldowns. At least with prot paladin you have god aura, bops, and some raid EF's in a pinch. Mainly the bops and devotion aura though...shit is just amazing.
It's easy to play a monk tank, but fairly difficult to be a godly one. Warriors are kinda meh since cataclysm and bears are just super low in representation.
Prot paladins just stack haste...that's really it. Defensive stats suck dick, it's like a rogue with a shield...that can solo tank a lot of raid bosses including some heroics.
