Reasonings:

\---  
Most of the time depends: Endo is here because if we just dont take any flashlight animatronics, he is easy to avoid, but if you took a flashlight one then its annoying. Nightmare depends on if you are stuck on some part and how often the animatronics attack you allowing you to progress to next checkpoint. Lefty was my worst enemy until i found out about the trapping tech. Chipper depends on how many tokens you are earning but even then you may play a bit of minigaming. Lolzhax all really depends on who he gives to you.

The "Very Special Amazing tier" is self explanatory.

Not even a threat at all: Cant hurt me/annoying but non lethal. The reason for Felix and Funtime Chica here is because for felix i can just either not buy the upgrade or just not spend my tokens/farm them from negative, and as for funtime chica i can just deathcoin her or not use the gambling thing at all.

Easy to avoid: Self explanatory. Freddy, Bonnie, Chica, Foxy have soundcues and visual cues, golden freddy is just put on the mask quickly enough which you can do every time after you pull down the monitor, Toy Freddy can be ANY minigame so i just do circus sorter or cupcake clicker, toy bonnie is easy due to his voicelines, Mangle is here because i mainly use cameras for minigaming really and thats it, BB and JJ have voicelines, Puppet has visual cue, Withered Bonnie has a soundcue and even better if you already were in the office especially with the mask on, Withered chica is easy because sound cues, so is withered foxy as well as long as you dont have too many threats to deal with, Springtrap has a sound cue and you can just check time to time, Phantoms are the same as mangle, Nightmare Freddy and Nightmare chica have visual and sound cues and the whole game thing isnt even fully on your screen to cover them really, Nightmare BB is just spam click, Baby is easy when you dont have a lot of threats, Circus baby has sound and visual cues, Molten Freddy sound cues, Mr Hippo sound cues and isnt even lethal either way, Twisted Wolf and Dreadbear have sound/visual cues respectively, do we even count the fan as an enemy? If yes then just turn it every so often, should cool me right back down \[Get it?.. That was funny right-\]

Mid/forgettable: Toy Chica may be a bit forgettable over time and there may be a lot of threats to overshadow it, Nightmare Bonnie is easy as long as you dont have a bunch of annoying sounds and is slightly forgettable tbh, Nightmare foxy and Candy are basically the same thing - may be forgettable and annoying but have visual and sound cues, Ballora is forgettable since she doesnt spawn minireenas instantly and instead throught the night i think?

Really Difficult/Quite a challenge: Salvage may be annoying depends on how many and what threats you have but is mostly simple. Foe FredBear is a challenge due to reaction time it needs you in the boss battle and the same threat thing.

Withered Freddy just never salvage him never do it never touch him it was the worst mistake of my life.
