It was just a rez, now you can use it as an absorb also.  Dark Armor has a lot of other mitigation so it doesn't *need* to have an absorb up 100% of the time.
 
	 
 
 
	 
 
	Do you mean Cloak of Darkness? That defense does not supress. CoF doesn't have defense.  However, CoF does have knockback protection, -damage and -tohit (as well as the Fear mentioned in the name)
 
	 
 
 
	 
 
	Depends, I used to take OG and skip CoF.  CoF is a lot better now though, so I swapped to taking CoF and skipping OG.  Except on things like my DA/Stone tank who stacks AoE stune between OG and Fault.
