Is wallhack perks fair?

Survivors arent allowed to have variety in their gameplay.

I need to address the elephant in the room here: people complaining about parts of a Killer power designed to give info, i.e. Killer Instinct. If it's part of the power, then it's balanced because it's part of the power, and therefore CANNOT be "unfair". Killer powers are designed to be fair. Let's look at when and where some Killers get this, and why:

• Ghostface gets Killer Instinct whenever he is revealed so he can chase the Survivor that did it. This is because Revealing is part of his counter, and without it Survivors could hide and he'd never know where the person revealing him is. There's even addons that exist to capitalize on being revealed (which means no, it's not a bug or downside pr a problem at all - it's a feature and a good Ghostface will use this feature as a tool; he's supposed to occasionally be revealed).
• Sadako gets her Killer Instinct when a Survivor nearby is ready to be Mori'd by the Condemn mechanic, particularly when they put a tape in the TV. This is to help guide her to someone she can chase and then reward her if she gets the Down for using her power properly.
• Dredge gets Killer Instinct during Nightfall whenever someone is close to a locker or their remnant in Nightfall. This helps the Dredge find Survivors they can chase during Nightfall, when they might be more vulnerable, giving them the element of surprise. Killer Instinct is notably not blocked by lockers, so this may be intended to also show when a Survivor is opening or getting into or locking a locker.
• Legion gets their Killer Instinct during Feral Frenzy to help guide them to Survivors nearby (within TR range) to hit and continue their streak. This is an intended part of their play and meant to eventually reward them with a free one hit down if they manage to chain five (though that's quite rare).
• Pinhead has Killer Instinct with a special overlay that tells him whenever someone is solving the Box, so he can teleport to it and interrupt it if he wants, either to juggle the Box for a Chain Hunt streak or as information to find a new Survivor. This is the counterplay to the Survivors being able to do the Box.
• Twins gets Killer Instinct whenever Victor is out and there are any Survivors moving around or in the Dying State within Victor's Lullaby range, which is intended to help them find Survivors for Victor to pounce on or any Survivors that crawled away, since Victor is very tiny and has a low camera.
• Demogorgon gets Killer Instinct when a Survivor is close to a portal. Pyramid Head gets it when someone walks over his Torment Trail. Both are meant to indicate to the player either where they can find a Survivor to chase, or where someone who can be sent to a Cage of Atonement or Mori'd is.

So as you can see, Killer Instinct is completely fine and fair, because it's always used as a mechanic to aid the Killer towards getting into new chases or providing some power based benefit or reward. It's not cheap or wallhacks since it only lasts a few seconds, and it's certainly not something unbalanced that needs to be counterable, especially because we all know what Survivors tend to like to do if they cannot shake the Killer in chase themselves - hide and hope for hatch. It is ALWAYS meant to make playing Killer much less frustrating or provide information on who to chase next. It's usually because the Killer does not have a super strong chase power either, or has mobility but no way to tell info while in the mobility option.

Edit: You can downvote me for this take, but it doesn't make Killer Instinct less fair. A Killer Power that is balanced, and most every Killer is balanced, cannot be inherently unfair. You are not supposed to be hiding from the Killer easily all round, mid chase, or any other time. The Killer is intended to chase you, info helps with that. If Iri Keys with blood amber are fine, so is Killer Instinct.

Also correct. I believe Spirit also gets it if she runs Cherry Blossom. Wasn't trying to go for every Killer that has it though.

Trapper, Pig, Ghostface, Legion, Clown, Doctor, and all other low tier Killer picks don't need to run these perks at all?

Do you really think low mobility Killers can win against a team of stronger Survivor players that can coordinate well enough to make gens go by quickly? you TRULY think all Killer players just want Survivor players to suffer?

… oh no, friend… you think KIllers don't play Survivor too, don't you? You actually think Killer players WANT to hurt people… I'm afraid you're the one with the misconception here. Most Killers only run these perks for three reasons:

1) Their Killer does not have mobility and they face decent teams often.
2) They aren't confident at map pressure yet.
3) They're a setup Killer that may need the extra time to prepare.

None of those are about making Survivors feel bad. Nobody runs Pain Res to make you feel bad. The game isn't about you.

While I agree none of these Killers should rely on tunnelling you continue to miss my point. I did not say these Killers have to do this. I said if someone is a weaker Killer player overall, they may feel the need to do this.

Most people are most certainly not all playing S tiers, go look at the pickrates sometime. There's still pretty high pickrates for Killers that are strong but not S tier (Dracula, Wesker, Huntress, etc.) and the pickrate for a fair few of the lower tiers is also higher than you'd think too. In fact some very strong killers, like Artist and Twins, are hardly ever picked at all… which disproves that claim that "everyone just plays strong Killers".

You are correct that many Killers don't learn their kits properly, which is why the phrase "weak Killer" is and always has been an oxymoron. No Killer is weak - you just might not know how to play them yet, or effectively. It's not the Killer's kit, it's the player.
