Core Issues With 4.x Dark Knight

[SyzzleSpark]

Hmm... what if we did this:

->Remove TBN's MP cost.
->Remove TBN's Blood return upon breaking.
->If TBN breaks, cut Shadow Wall's recast by 5s. (If you spam TBN and it breaks every time this would whittle Shadow Wall down to about 120s recast).
->Add +50 Blood Gauge effect to Dark Passenger. Potency and MP cost unchanged.
->Halve Delirium's recast.
->Halve the duration increases to Blood Weapon and Blood Price granted by Delirium (+4s/+8s respectively).
->Sole Survivor = Medica II on 120s 90s recast.
