DRK changes that would make it really fun to play

[Flay_wind]

Dood, which part of the suggested changes is supposed to be fun?
That would cause so much unnecessary headache i am not even sure where to start. 3s casting spells? On a TANK? What if you need to move? Or mitigate next attack? Or you're forcefully moved by a knockback effect? What if you need to look in a specific direction? All of these would interrupt the cast.
You want to remove Dark Mind and Dark Missionary and leave OBLATION untouched? I'd want some of what you're smoking.

Edit: Also what were you trying to achieve with this?
Abyssal Drain:
AoE HP absorb. 3.5s spellcasting animation. Cost: 6000MP. 90s CD.
