If you think about it, the "beacon" is sort of the gate/portal, as it opened the way into the Dragon Isles.
Class devs are seemingly given free reign to fix the classes the way they want. The hunter one (who I think also is in charge of Shaman) is just the most active in terms of Blueposts. The Rogue one is not as apparent, but supposedly very active on the class Discords.
In a sense it's just luck of the draw sadly, some classes got lucky and got great developers who want to do good work, and some like Druid got unlucky and had the developer leave the office, whether for vacation or permanently.
That being said I think the Warrior one was supposedly in quite a good place comparatively, so that developer might just be focusing on other stuff, they do afterall take care of more than one class at a time.

I think in theory a carefully-crafted talent tree would make it possible for each player to choose more necromancer or more towards knight, but I doubt it'll happen, at least not currently. Personally I prefer they lean into the necromancer side, mainly because it just matches the theme better and further differentiates the spec from Frost, but also because it's cool.
That is true, it's just the framing of the login screen that is way off. No clear central motif, no apparent continuation of the portal theme. Might be different once I see it animated though.
That being said, I guess it's only a small thing anyways, I barely ever even see the login screen between logging in from Battle.net and going to the Character selection.

Might just be me, but whenever I play Unholy I always feel the melee stuff just gets in the way of the Necromancer theme. I want to see my diseases spread like a contagion, and summon ghouls to overwhelm my enemies, not laboriously give my enemies zits that I can pop.

Personally, I don't like the wound mechanic. It slows down the spec and makes it feel like I'm constantly setting up for damage, rather than doing damage. This is only further compounded in open-world content and pvp, where I find the spec cumbersome and un-intuitive. Add on Unholy being a Pet AND a dot spec just makes this worse. There are also too many cooldowns (Transformation, Soul Reaper, Army of the Dead, Apocalypse, Unholy Frenzy, Gargoyle), so when they aren't up, I feel like I'm not really doing anything, which is made worse by the fact that I need to "set up" my wounds to feel like I'm doing anything in the first place. The large number of cooldowns only exacerbates the GCD as well. The flow of gameplay seems to be too much of setting up wounds, wanting to spend them, but being interrupted by higher priority cooldowns.
The abilities and feel of the spec just feels weak, even if I'm topping meters - there's too much damage spread out, so the spec feels like "death from 1000 cuts", which seems wrong for a Death Knight. I would remove army of the dead and spread that damage into more commonly used abilities like Scourge Strike / Death Coil. Plus, the spec is slow and immobile and doesn't feel particularly tanky, especially compared to other classes like DH, monks, or warriors.
Too much of the ghoul is passive as well - it would be nice to have some sort of kill command-esque ability for the ghoul, rather than just hit a button every 40-60 seconds. The ghoul is just window-dressing at this point and doesn't feel like I'm doing anything with it. Maybe give us a KC - like ability that serves as an execute? Sense Death or something like that which makes the Pet feel impactful in some way.
Also, Unholy has really weak animations / spell effects. The fantasy is great, the spec just lacks any sort of "coolness" factor. Give me bigger and better pets, and more of them. Give Death and Decay a new animation (Why is this using the same effect as Blood?). Make scourge strike cleave the same animation that Blood has for Heartstrike cleave. Clawing shadows should release some sort purple claw from your weapon. There's a lot of potential here, and I would look at the necromancer in D3 for inspiration, but right now the only cool looking ability is Apocalypse then some random green auras from WoTLK to indicate a disease.
I agree with most of your points especially when it comes to "too many cooldowns" (you're setting up for like 10 GCDs every boss fight) and the animations. God the animations are weak. They just don't have any shine or kick behind them, there's close to no difference between a normal melee hit and Scourge Strike.
I also feel like Clawing Shadows is such a misplaced talent, Sure it's nice to attack from range but except for Death Coil there's nothing else to do. Would love it if they explored that a bit more.

Damn the Monk tree feels good. Especially the class tree. I just don't agree with the Roll placement. And it seems to be only 1 charge baseline.

The talent locations of Black Arrow and Legacy of the Windrunners have been swapped.
Uhm wait what? did I miss black arrow being added or is it a typo? can't find it in the tee.
