If you were to change COH, DH and Medkits differently from how bhvr did it, what & how would you?

I would remove all the perks and create perks that do not change the overall aspect of the game or the balance of it.

It means perks that cannot be META, exactly as VHS did with the weapons or monster's perks, they just give some flavor without changing/breaking the gameplay.

Same for the items, no self heal allowed, only healing others but a little faster or with less skill check etc...

If BHVR would stop going back and forth between gen regression and healing with nerfs and buffs and instead focused on making the matches a more interactive push and pull of a round. The weak killers continue to stay weak, solo q is a nightmare even with the hud buffs, and patch after patch one side is furious or the other because at the end of the day both sides just want to have fun and while there are addictive, and sometimes enjoyable moments, it just feels like we are all just searching for that high we originally experienced when we started playing.

All they had to do with Dead Hard was make it unusable at exit gates similar to DS or put a cool down when it's used at pallets so that it can't be abused.

As killer, it's great because it can't be abused anymore and you can really see a difference in the game from that standpoint.

As a survivor, I'm still running it but I'm running it as a secondary perk now. I can see why people wouldn't wanna run it at all though

Rework the objective on the survivors side so that there are multiple different ways to power the exit gates that are more than just holding m1. Tie the ability to complete those objectives with charges surv can earn by being in chase with the killer or by retrieving them from chests or cleansing totems. The survivors start the trial with enough charges to complete 1/2 of one of the objectives (for reference, half a gen) that need to be done but in order to do another they either have to go interact with the killer or find something to recharge their charges.

Something along those lines.

I would’ve differentiated the different medkit rarities a bit more. A purple medkit is hardly any better than a brown one right now. Other than that, I think the changes are mostly fine. CoH self-heal needs to stay gone, forever.

The Dead Hard nerf is fine. It is not a strong enough perk anymore to justify using it over other Exhaustion perks, which was the goal, as that encourages perk diversity. You only get to use DH at most two times in a trial, which is already a huge downside over all the other Exhaustion perks, which shine precisely because you get constant value out of them. Even more importantly perhaps, you don't get to use it in the first chase, and the first chase is usually the most important of the game. On top of that, Deep Wound nullifies DH, so if you get tunnelled off hook it might not do anything for you. If you get camped on hook, you might only get it one time, or never. If you don't get hooked before the round is already in its concluding stages, you might also never get it. And then on top of that there's killer abilities, perks, and add-ons (as well as latency...) that can rob you of your chance to make much of any use of your DH even in the limited instances where you have do access to it. Same for instadown/Exposed, should you heal after getting unhooked.

Given that, I'd even say DH could be back to 1 second duration, and unhook endurance should become unhook invincibility (with removed collision).

DH can still be used, but I personally wouldn't use it without also using another Exhaustion perk and Decisive Strike alongside it, which already takes up 3 perk slots.

Circle Of Healing was overnerfed, in its current state it is not worth using. I would simply make it so that it enables survivors to heal at normal self-healing speed in its range (32 seconds), and limit the 50% healing speed boost to altruistic heals. I don't ultimately care so much that Circle is gone now for its own sake (although it had been a bit of a saving grace for solo), but with it, the other Boon perks are not viable anymore either, as those had really only been worthwhile alongside Circle. So at the very least, I would buff the other Boon perks now, such that anyone would even consider spending the time to find and bless totems just for those.

Med-kit nerfs are welcome, but BHVR's approach seems very haphazard. Now all med-kits are virtually identical, and most add-ons do nothing whatsoever worthwhile. I think they could have kept the charges how they had been, and simply made self-healing with a med-kit take 32 seconds. Then add-ons could be used to more significantly change the purpose of med-kits, with some add-ons allowing very quick self-heals but coming with charge penalties such that you can only get one heal out of it, or others that disable the ability to heal yourself with the med-kit (or increase the time it takes to do so significantly), while increasing charge efficiency and healing speed on altruistic heals tremendously. There could also be add-ons that show you the auras of injured survivors and their healing progress indicated by their auras, or show your aura to injured survivors, or that grant bonuses when completing a heal with the med-kit, such as brief Endurance or Haste. There's a lot of things they could have done that would make med-kits much more interesting and exciting than they are now.

CoH I'd have left the self heal in place. I'd have removed the ability to stack speeds with any other perks/medkits. Lastly I'd have given it a token system. It can only be lite 3 times. It deactivates if snuffed or after two heals.

DH didn't need the nerf imo. Sure it was annoying but it wasn't that hard to bait.

Medkits are a bit more difficult. I think I'd have left them alone with one exception. Self healing with a medkit takes 24 seconds. The only exception to this being the Emergency kit.

As for how I'd improve the rest of the patch:

CoB and OC would stay the same. Gen kicking perks no longer stack regression.

Pain Res I'd have kept the same except I'd add a token system. You'd start with 1 token and gain another token for every 2 hooks you get.

I'd extend DH's duration to 1s, but make it provide Endurance only against Special Attacks. This would help flatten the effective range of Killers so that you can't use DH against Trapper or Clown, but can still use it against Blight and Nurse. (To that end I would also make Spirit's M1 out of phase be considered a Special Attack as long as you would get the score event, or roughly 3-5s.) This would make it so as Survivor you might risk a dead perk against a Killer, but instead of the perk being useless against a strong Killer (EG. Healing vs Plague), you only run the risk against the weaker Killers. It would roughly balance itself out.

CoH is perfect, arguably with a 25% self-care speed so you could still solo heal, but people would be incentivized to heal you instead of allowing you to take 64s to heal yourself.

Medkits I would have kept Green's self-speed boost and at 16 charges as well as Purple's 32 charges. It would still take 24 charges to full heal yourself, so you would need to bring an add-on with them for selfish healing. Also Pharmacy would need to be adjusted to put the 8 charge bandage add-on also, to still allow for a self-heal. I also would make the speed boost add-ons have an equal altruistic boost as the universal, so altruistic med-kits are more incentivized even in the add-ons.

As a side change I would revert both sides' double nerfs done in 6.1.0, down to single nerfs instead. Eg. Pop buffed back to 20% max, DS at 5s, Iron Will back to 100% OR non-exhaustion, Ruin back to 200% OR not be removed on Survivor death.
