Suggestion to fix dark knight (actually good)

A change that my friend thought up was to change dark passenger to have and additional effect instead of blind, to mitigate damage like the old delirium effect dark knight had, maybe 10% for 5-8 seconds and it would have the same mana cost but maybe a longer cooldown. This along with some potency increases would put them on a much similar level to the other 2 tanks both having aoe mitigation for the group. It would also make dark passenger actually usable rather than a useless skill in 99% of situations (similar to what the old shake it off was like for warrior)

I'm not really interested in savage, and the point isn't to increase DRK's DPS output. It is more on the impact it has in ultimate and yes, it has less impact than the other two tanks. Especially for something like golden bahamut phase where the mitigation rotation is pretty tight and having DRK makes this phase in particular extremely difficult compared to having WAR/PLD. This is not even including other phases like blackfire trio where having an extra shield like shake it off can help with the amount of damage being taken while moving. DRK seems to under perform in this department where it becomes a hindrance in these situations.
