I agree that damage migration is important. Indeed, both hate control and damage migration need to be considered.

However, damage migration enters the equation if and only if the character is under the mobs attack (except AoE attacks). IMHO, the prior for a tank should be:

1st: Holding hate.
2nd: Damage migration.

The amount of damage migration that a tank needs, is determined by damage output of the mob, tank's hate control, and how fast the mob dies.

As for rate of shield proc, I don't see any noticeable difference between shield skill and proc rate. On the other hand, I can see some different with AGI+ (shield skill caps faster), and a very noticeable difference with shield size.

If DRK/PLD's shield is not functioning, then the DRK/PLD can go back to G.Sword or Scrythe... or maybe Break-WS from G.Axe too, Full-Break and Absorb-TP sound interesting

As for Enmity+, I think gear more towards DD may be an alternative (a mix of Enmity+/DD/tank)
