Specifically a revision for William Afton and a weakness/durability edition for the animatronics. So for William his core reasoning for 9-B falls under accepting this part: "Easily tore apart each animatronic on his own." Now while I already am kinda iffy on using the atari style minigames so say how an event exactly happened since they're meant to be depicted vaguely, that's not the reason I'd call for a revision as that'd be a little too weak of a reason.
The actual reason is because the animatronics durability has a weird asterisk to it. Specifically because of the existence of The Mangle. Now contrary to popular belief, the Mangle was NOT designed to be taken apart and put back together, the staff just eventually made it like that because they were sick putting Mangle back together after the kids took Mangle apart every day. For reference too, the toys are the animatronics they spent a small fortune on them and have a bunch of advancements and the FNAF 1 animatronics are even given some of the toy retrofitting so the Toy Animatronics are considered the most advanced thing they have during the FNAF 1-4 era. This is to say that Mangle weakness applies to the other animatronics since it wasn't even made in mind to be pulled apart and put back together, it just happened to be since they let the kids actually touch that animatronic unlike the others that's what started happening.
So we know that means you don't need to be 9-B to tear apart an animatronic they can easily be taken apart by kids and we know the Atari minigame is already naturally a more vague depiction of things since something atari-era based can only show so much. We also know William is realistically sneak attacking them, yes I know William can do things like attack them even if they don't go to the room, but that's realistically a means to troll the player for not following the set path and is somewhat of a gotcha moment, realistically and narratively he's sneak attacking them.
I mean think of it like this: If William could easily tear apart the animatronics without even need to sneak attack them, why would he even be hiding in the backroom? He'd easily just tear them apart why they're offline on the show stage since they only activate one by one.
All in all, he needs to lose his 9-B reasoning for this since it's based off the assumption that he is easily tearing apart the animatronics when in reality there's a lot of context missing.
Animatronics themselves need to get a lower durability specifically against pulling or tearing parts of their body since even toddlers can do it. We also have scenes like Gregory kicking away Chica and he's just a kid.
Also some durability reasonings need to get removed:
"Comparable to other animatronics, which are unharmed by a car crash that broke through a billboard"
Those are security bots and this is a gag scene, you even see the windshield wipers wipe them away, something that makes no sense when windshield wipers are not strong enough to do that.
"Survived Fazbear's Fright burning down."
The building was plenty intact so it's not really a survival, the usual reason this would kill a human is due to the loss of oxygen and soot filling their lungs, but since these are animatronics that doesn't really mean much for them.
"Survived multiple rounds of fire"
This is first resistance.
"Wall level (Should be more durable than the animatronics)"
This completely has to go.
So all in all, 9-B removed for human William Afton, and a lower durability reasoning listed for animatronics outside of their natural wall level durability since they have ways to be affected by lower characters and a weakness section on top of that.
