The strength of Hex Perks...

I stand by the argument that hexs should be strong enough to warrant to search for. Thats like saying you will run red herring over diversion(Not the best comparison but bear with me). Red herring is weak and will likely get no use while diversion has a chance to actually get a play off of it. Nobody wants to waste a perk slot for something that won't help them. And as for the "do bones" response, you could honestly bring a map to not waste a perk slot if it becomes repetitive to keep finding totems

If your not gonna break totems then you shouldn't have any issue with the strength of a hex. A hex being to strong by itself is laughable because you can destroy it and none of them give the killer any pressure until conditions are met.

Make hex worth the risk and drop the ridiculous drawbacks.

The current state of the game IMO, is that hexes are so weak that a huge number of survivors do not even cleanse lit totems. Personally, I don’t see how anyone can argue that any of them are too strong at this point. If it were up to me, I would definitely increase the strength of hexes quite a bit, and have a much larger variety of them. I believe each killer should have a hex in addition to their regular perks. Just to be clear, I am a survivor main, and I only play solo queue.

One big thing they could do is simply to remove hexes from the blood web, make all of them only their full strength, and allow each killer to equip up to two hexes in addition to their regular perks.

Every perk is a balance between payload and counters. Some perks are either not particularly strong or self-regulating such that an active counter is not needed (Autodidact holds itself back, Adrenaline is kind of countered by NOED). DS can be countered by 1) not tunneling 2) let's be serious, just slug. Unbreakable is a pretty meh perk in most circumstances, which is why its counters are pretty sparse. It's the opposite of the hex perks: highly variable payload, consistently difficult counter. Botany knowledge isn't great, We'll make it times itself, and the exhaustion perks have the exhaustion status effect.

Hex perks do away with this fragile balance by replacing the counter with a prayer to RNGesus. Good survivors will get used to  totem spawns, and then it's gone. The strength of its counter is heavily dependent on chance. That's why I never run devour hope; it requires a large amount of time to even become useful, all the while being vulnerable, for a pretty good, but not excellent, payload. In many cases with hex perks, the payload is simply not good enough. Huntress' lullaby is the definition of useless, ruin can be excellent in certain builds but usually gets cleansed in moments, retribution is simply not powerful enough to be a hex (or even a non-hex perk), haunted grounds usually only gets you one down and rarely any more, etc. I can understand the idea behind them, and I think it's a great idea, but they just are too inconsistent to see constant use. I generally think that a buff would be to lower the counters but also nerf the perks. Built-in old undying would be nice for something like 80/90/100% regression speed ruin, 7/6/5-token exposed devour hope, undying that only includes the aura reading and token retention, current-state third seal, lower token requirement huntress' lullaby, etc. 

The Undying nerf is more or less telling on how the devs view hexes:

They think hexes shouldn't be meta relevant.

Hex Undying was the only viable hex defence perk in the game that made hexes work as their design would intend being powerful but removable effects.

All previous hex defence perks are objective failures such as thrill and retribution doing nothing ultimately to truly defend/deter hexes from being destroyed.

However with Undying's nerf it's really telling that the developers just don't want hexes to be part of the meta at all as the only perk that made a non game breaking hexes meta got nerfed into the ground which will destroy the current hex using meta as lets be honest DH won't be meta.

TLDR: It just feels like hexes at this point have become failures in the dev's eyes and they want to bury them with nerfs so they don't have to deal with them anymore(Like they did with billy/nurse).

Hex perks should be strong if they can be cleansed in the first few seconds of the game, at that point the killer is now down to only 3 perks and they have no way to change it. You cant have the perk be high risk with no reward, then there's no reason to take it over a more consistent perk. One perk that comes to mind is Hex: Blood Favor, a hex with so many limitations its not even worth being a hex at this point.

Its a good day when the Hex totem doesn't spawn next to the survivors.

Do bones is usually in response to NOED than any of the other hexes.

Hex perks realistically are going to be up for about 1/2 to 1/3 of the match, and thus give huge value to compensate for not only being unreliable but for being able to be completely destroyed. The two hex perks actually worth running give enough of a payoff to be worth using despite the fact that they can disappear anytime during the match. Devour Hope and Ruin.

Other hex perks just aren't worth running. Thrill of the Hunt on its own does literally nothing but help a killer farm. Third Seal is nullified by SWF, needs to be built up, and barely matters because survivors still get a big alert when someone is hooked. Blood Favor is countered by survivors moving to a different loop because its range is small. Retribution is unreliable and uncontrollable, often working as a worse Bitter Murmur. Huntress' Lullaby is... lol. bad.
