I just had to skip a lot of the stuff because I'm not gonna read 20+ pages right now :/ But here is some of my own opinions, which I'm sure will help a lot.
what I think should be is more configurability. there is the 'simple' version, then an option for 'advanced.' Advanced goes into far more detail, split by catagorys including a search bar. Simply is more of the basics.
One of the main options should be a 'mode' type. Part of that has to do with things being 'nerfed,' so there is Nerfed mod and then the mode without it. And also an option for 'respawn,' for those milk drinkers who can't stand permanent death. Seeing as skills are capped now, one of the modes includes no-skill-caps also. With advanced mode these things can be changed even further for more customization!
Of course, advanced is visible but not in the way, and you can do a lot of changing without going in there to deal with a bunch of extra bits.
I've found that in terms of filthy clothing, it's much more worth making your own stuff usually instead of find things. That goes for more than clothing too. Why scavenge for clothing from houses and off zombies when you can make your own stuff to the point of being a modern-day knight with a flaming sword and hulkish-mutant-muscles? Or a nomad on a death-cycle with a laser-pointer crossbow? Turn your NPC friends into walking-talking-meat shields by giving them OP (but combursum) armor so you can run away in a dangerous time! Among other things.
I'm still trying to figure out the whole gun-thing now. I don't understand why my gun will work at some point and not at the other. But reloading my shotgun multiple times is really annoying. What's the point of that? I should change to something like - 'reload all the way?' or just assume you want to reload all the way and if you stop doing that task it is only partially done.
NPCs are much better, and I like the idea of them needed to eat and stuff. it makes sense. BUT GET YOUR OWN WATER AND FOOD YOU LAZY BUM!! I have some ready nearby you idiot! You should also be able to teach your followers stuff that YOU know. You should be able to give them a command of scavenge stuff for yourself that isn't allowing them to pick stuff up!
I have found the game be a major pest when I'm trying to do something that takes a long time, (Like dissasemble thread) Becuase it keeps coming up with something like: "You spot a zombie nearby. Stop crafting?" No. Never for a regular zombie when I have 10 dodging skill. They LITERALLY cannot touch me and I don't care about a hundred of those things trying to fight me. There needs to be an option of 'ignore everything?' or 'ignore everything unless hurt by something that is not poison/coughing ect.' I can't do anything about me coughing right now, and it doesn't matter enough to me either!
Expiramental is the new stable...
That thing needs to be fixed where missions keep breaking because of the fact that I'm TRAINING.
Is there a flaming zombie? There is an acid and a spitter, why not flaming? Honestly I'd hate that but still...
There should be a way with the tailors kit to modify clothing so that it give environmental protection also. You can give it warmth and defense, but not enviro-protection?
