OK, well I have tested out all the tanks I have (not Monk) and here is my conclusion.

The paladin seems to be the best tank. period. The DKs are fantastic, and like Remanz said, they can solo a boss if your team dies... in fact my team died on the rabbit boss when he was 75%HP, and my DK just killed it (after a few centuries). However, the DK seems to take burstier and less reliable damage, even with a mitigation gearing. One of the problems, is that Blood shield is hard to time as a boxer, with all of the other things going on, it's difficult to make use of the best ability to a DK, Death Strike. You should use this AFTER you take a bunch of damage, healing you and shielding you for a ton back. This is a great mechanic, but it's easier said than done when you are busy tanking the boss, and DPS / healing / cleansing etc. In the FCFS rotation, death strike will go off, but there is no guarantee that you can get a good hit from it.

A Paladins abilities are all no brainers. It's better to use Shield ability right before taking damage, as it reduces damage taken, but it has a good uptime anyway.

DKs and paladins do similar DPS in a dungeon so far, too. I still have my Ret paladins doing about the same damage, at lvl 87 it's about 20k on the tank and 19-22 on the rets. Getting better


Anyway, these are my feelings so far. Anyone with a Monk 85+?
