Spectres don't feel great

I imagine most people agree on this, I haven't seen many people saying positive things about the spectres so far,(a few outliers i.e Vaal Guard) But things don't change unless enough people complain about it, so I'll add my voice to the cacophony and hope GGG is listening.
I've done my own testing, but use a spreadsheet created by Truditoru on youtube for most of my spectre knowledge. I believe that spreadsheet alone covers most of the issues found by players. Biggest issues are these:

1. Spectres getting stuck in wisp form makes playing with them feel downright awful.

2. Spectres cost too much to be benefical. Out of 428~ spectres, only 37 have a base spirit cost less than 50. While the most expensive skeleton (brute) costs 51 spirit. This on its own doesn't have to be a bad thing, but...

3. Spectres are typically very slow, and/or don't have the damage their spirit cost would suggest they should have.
Example: My Knight-Gaunt (because his design is far too nice *not* to have in my undead army) costs 110 base spirit. When compared to having 5 skeletal warriors a few archers/mages or a couple of brutes that do more damage, don't get stuck and aren't slower than a solar orb. The trade off doesn't feel worth it.

The spectre system is one of the big things that puts POE above others in this genre for me, and is why I started playing the game. I'd like to see some major improvements. Thank you for reading.

They have no love for minions. Believe me. People had so much fun with minions in poe1 and patch after patch they nerfed those to oblivion. What's supposedly easy gameplay eventually became totem style gameplay.

When 0.1 first came out, first thing they did was nerf arsonist. They didn't bother nerfing spark and that became the meta.

They further nerfed minions this league when it wasn't even meta.

They are so worried about minions being OP but are ok with LS being as meta as it gets.

I'm not sure if I'm crazy to think all that, should I visit the head doctor?

Frustrating to hear that. I don't need minions to be the meta, or even among the best builds in the game. The spectres just need a bit more love and some player favored tuning. A reasonable goal by the end of early access for GGG here, I believe would be to make at least 200+ spectres viable for end-game content. Obviously not every spectre is going to be a good performer, and there's nothing wrong with that. But I think the player conducted research I'm referencing suggests only about a dozen spectres viable for mapping.
