Legitimately still confused about why, if the purpose of new Delirium was to give DRK a burst phase, they didn't just make it something like a 20s, 20% haste buff that would fit with the pre-existing flavour of the class instead of an inferior Inner Release for Bloodspiller, a skill that doesn't even look very nice when spammed. Maybe they didn't want DRK to ever get more than 5 gcds of the new Blood Weapon? But that skill could just work like Bunshin's stack system, and probably needs to for QoL reasons.
