Blah blah blah, duh there is more content comming for Dark Knight and all other jobs, this isn't the end, blah blah, SE Quote:
Anyways, with that out of the way (and ignoring DRK QQ, especially from people who think the job posted on your profile means jack about wanted to see better things for jobs), this is pretty much a suggestion/discussion thread now, right?
The main thing I see (and I totally agree with) is a general want for more magic usage that isn't a waste of time. And this is hard, especially since the magic has to win or at least help the melee aspect, considering how good melee is compared to casting tier 3 nukes with no native magic attack bonus.
Suggestions from the OP:
I don't know how likely Absorb stat spells are to get a boost, but considering SE said spell space is limited, a formula rework would be nicer to see then a non-broken tier II in my opinion, even if it was something silly like "Dark Magic Skill above 400 = not broken!"
On lowering cast times, I believe one of the Relic+2 pieces is slated to get a direct reduction to Dark Magic cast times, which could help a little. Some more fast cast options built like this would be nice to see too however (or even spell adjustments if need be!).
A new Stun tier sounds like a good idea.
On a new Drain tier, and on something that is a good idea for Occult Acumen, I have an idea that might work. It wouldn't be Drain III, but a new spell that does get health back. Admittedly, it is more of an ideal (measured with an eye to balance) then something SE would likely give to Dark Knight.
It would be called Absorb, and have a fairly long recast of around three to five minutes (I'd prefer three, but considering the desire to spam this, it would probably end up with five, especially since spells are affected by haste, unlike job abilities like Konzen-ittai). It would take about one second to cast, and would do somewhere in the neighborhood of 400~1500+ damage (the important part would be that on a partial resist it would reliably get at least 300~400 damage, the upper numbers would probably require solid gear combinations on slightly weaker mobs). This would then be added to both HP and a portion to MP (Not subtracted from the HP amount, but a fraction of it. Ideally if the spell does less damage, it returns a larger fraction, but if it does more damage, it returns more MP, but a smaller fraction of the damage). The spell would cost 400 MP. If SE was feeling really generous it would also debuff the mob's defense for a very short time too.
The idea behind this is primarily a spell to exploit Occult Acumen as much as possible while still retaining a sizable chunk of the MP used to cast it and even doing something extra Dark Knighty. Ideally the spell would return at least 200 of the MP used, and in ideal situations even grant MP back to the Dark Knight. This would be ideal when used in skillchains, and my only regret looking at it is that you wouldn't be able to burst it on the self-skillchain you'd make possible by using it. It would even cause risk with this (a DRK ideal!) by causing a lot of spike damage for careless Dark Knights.
As a side note, I'm happy to say the last pick up VW group I was in wasn't so selective and was still very successful.
