TBN: The absolute last thing we need is more homogenization. Remove the MP cost for all I care but do not increase the cooldown.

Living Dead: To be fair, it does...the only conflict is you have to actually die first for the effect to take place, and if you get that low healers are likely to panic heal you.

Delirium: I actually want our MP regen skyrocketed, but...not like this. At that rate I'd just like old Blood Weapon to come back with the haste buff.

C&S/AD: agreed on decoupling them, but Abyssal Drain actually already does heal you? Just make it a spell again or reduce the CD on it to 30s with two charges.

Delirium part 2: We truly do not need this level of sustain you are suggesting.

Salted Earth+Salt and Darkness: Would be pretty neat if Salted Earth was mitigation and Salt and Darkness had a low potency heal, sure.
