DRK Sustain: A Choice (+Grit change)

Hey all, I want to voice another idea for DRK and its self healing. It's about a little change to Delirium and Souleater.

I guess I'll just get straight to it;

* Instead of Delirium only extending Blood Price in Grit and trading blood for MP, it would still extend Price but instead of giving MP it'd heal the DRK for 1200 potency. Now I know this isn't completely in line with DRK's "way", but, at this point, I don't think it that big of a deal. The animation permits it, at least, and adds some depth to the skill.
Delirium outside of Grit would remain the same as it is now.

* Souleater, out of Grit, should also absorb HP. Still not sure why this is not the case already, at least at a lowered percentage (50-60%).

* And finally, to make things a bit smoother, Grit should be a 5 seconds oGCD like Darkside. It wouldn't be super OP considering we still pay a hefty amount of MP to turn it on.

So that's all for now. Tell me what you think, what could be improved, what you like, what you don't like, etc. Thanks for your time.

Delirium giving life is a bad idea you can always spend some mana to get all of your delirium gain but you cant spend your life and will cause overhealing not to mention you can just use the 2400 mana to cast tbn.

Souleater not draining life outside of grit is stupid considering WAR and PLD keep their heals.

I'd rather have them remove the mana cost of grit activation putting it off GCD is nice but there is never a need to swap stances that much that it will matter while losing mana when entering grit in crucial points does.

Delirium looks like a heal, and it would be a unique element to DRK vs PLD/WAR regarding the 1,200 heal. That being for DRK: its passively used while maintaining optimal DPS (in Grit, which is bit of a contradiction).

But if the choice for DRK is no 1200 selfheal or a free heal with DEL if in Grit, then I'd pick the later.

I want delirium to be a second class dark arts with blood instead of MP cost.

Giving 280 potency to any skill/spell and make it cost free for 1 use, it could be used on darks arts so dark arts will give 420 potency buff to any still used with it.
That would be awesome.
