I hope SE reads forums and considers this feedback.

Disesteem : Good, functionally a step in the right direction, more interactions with Living Shadow are fun. Only wish they'd happen more often.
Plunge oGDD and 3 stacks of Blood Weapon: Plunge being used for mobility only is great but the MP generation should be addressed by either making each stack give 1000 MP or just give it 5 stacks like before. Losing things without anything to compensate is really bad, its not like the job isn't losing oGCDs ( 2x Plunge ) already.
Delirium combo : Sounds good, it separates it from Inner Release, which was heavily asked for, but perhaps it could've been made to be used outside of Delirium too, costing BlackBlood. The Bloodgauge is just a lazy copy of Warrior's Beastgauge, each action costing blackblood would be functionally different.
Shadow Wall upgrade: Amazing, finally some healing and sustain in situation where multiple hits happen.

Please fix the MP generation so we can still use a lot of Edge / Flood of Shadow, its one of the main ideas of the job. While we are at that, perhaps change Abyssal Drain to cost MP and remove Flood of Shadow so that Dark Arts grants a free Edge of Shadow for 1 target and a free Abyssal Drain for >1 target.
