4.1 Dark Knight Feedback and fixes

[Chrono_Rising]

I don't have my notes with me at the moment, but I believe delirium works out to be about 240 potency every 120 seconds when used with blood weapon, thats 2 potency a second. Basically we trade 50 blood for 2400 mana and 8 seconds more of blood weapon. This just doesn’t feel awesome to use being on a 2 minute timer, compare this to something like inner release, or paladin’s two buff rotation and you can see how lacking this ability is.
