Overall...I disagree, I think 5.0 DRK needs a bit more than what you listed to become a complete, enjoyable class. You\\'re right about removing the 60s cd on Abyssal Drain, I think this is one of the worst things about 5.0 DRK, Abyssal Drain just feels really bad and unsatisfying with that long of a a cooldown.
DRK doesn't need just "very slightly" better MP regen, it needs to be bumped up quite a bit. DRK's overall MP regen speed being butchered as much as it was is (I think) one of the main reasons why the class feels so much more sluggish and tedious to play. If DRK had a system of MP management somewhat akin to PLD's, I think it would work a lot better than what we currently have (all of PLDs spells cost 2000 mp, and a single Riot Blade combo restores 1000 mp). I'm just brainstorming here, but in this hypothetical new system, the MP cost of spells could still be 3,000, but Syphon Strike would restore ~1500 MP, and Stalwart Soul combo could restore ~1000 MP.
Also, 5.0 Delirium needs to go. Imo, it's the worst iteration of the skill yet. Aside from just being an unoriginal copy of a skill that already exists, its mechanic is just really repetitive, restricting, and ultimately, boring. It boggles my mind how most people who like 5.0 DRK (not necessarily referring to you @Lersayil, but I'm just speaking generally based on what I've seen and heard) claim to have utterly despised 4.0's Dark Arts spam, but are perfectly fine with this new Delirium essentially forcing you to do the same exact skill over, and over, and over again. Also, if SE is going to make Delirium generate MP with each of these moves, the MP that is restored needs a serious buff to make the function feel worthwhile. I couldn't believe my eyes when a Delirium Bloodspiller only generated 200 MP...that's just insane.
Personally, I thought Delirium worked fairly well in 4.0 when it functioned as a resource (MP) generator. In fact, in 4.0 your Blood Gauge was basically a resource that generated MP for you. I feel like that was a pretty good idea, and the cool thing was you didn't have to use it solely for the sake of MP generation, because we also had the choice to use Bloodspiller. I would like to see 5.0 build off of this foundation. Instead of having damage-only skills for our meter, I would have liked to see more of SB's restorative uses for it, or maybe even some PLD-esque uses that involve some kind of group utility.
Also, there needs to be another combo added, immediately. Even my buddies who have DRK at 80 already and love the class have told me spamming Souleater combo over and over just isn't fun, and understandably so. DRK is the only tank right now with only one single target combo, something needs to be done about that.
And for the love of God lol, can we make Fray actually do something interesting. Honestly, at this point, I think I'd take anything SE decided to give us. Just please, make Living Shadow more than just a glorified D.O.T.
