Change Delirium to make it a reverse bloodbath. You place the debuff on the mob, and 5% of all damage you do to that creature heals you.
This would give DRKs a role in the raid, whilst increasing their own sustain and tanking ability.
This makes 5% for example of the damage a black mage does to the target heal him.
This would help the raid's sustain slightly. Especially in large aoes where you need to heal quickly!
Probably 10% to the the Dark Knight and 3-5% to everyone else. I can see how it can get really powerful for some abilities, however it would be a fun debuff that suits the class.
