Ghostface buffs or nerfs? Devs are looking at him?

Probably nerfs given they just nerfed him.

its 1 second slower than before

old cooldown addons were 8 seconds + 6 seconds for a 14 second reduction or 16 second cooldown

new cooldown addons + base cooldown is 6 + 4 + 3 for a 13 second reduction or 17 second cooldown

Let's review his other addons then.

Philly, Telephoto Lens, Knife Belt Clip, Night vision Monocular (Reduce Stalk time when stalking and not leaning): So the base not leaning stalk time is 5 seconds. Running the Night Vision Monocular and Knife Belt Clip you reduce it to 3.75 seconds. Lean Stalk is 2.5 seconds. Ghostface should be spending most of their time stalking survivors while leaning. The only time you would not lean stalk is to pop a 99% stalk'd survivor or the game decides you can't actually lean. Not terrible addons, but largely useless when lean stalk to 99% is how you play Ghostface effectively.

Headlines Cut-outs, Olsen's Journal, Olsen's Wallet (Increased Movement Speed while Stalking): So as I said previously the effective way to play Ghostface is to lean stalk to 99%. While leaning you can't move so extra movement speed while leaning is worthless. At least the reduce stalk time while not leaning can help if a survivor isn't quite 99%.

Cheap Cologne, Telephoto Lens, Last Perfume (Increased Marked Duration): You can get +15 extra marked duration hitting 60 second marked duration on survivors. It's okay, but since you can 99% stalk survivors and pop them when you are close enough to hit you don't need extra marked duration. It can help if you accidentally fully stalked due to latency, but if you are already commiting to a marked survivor for over 45 seconds you are kind of throwing. It can help if you fully stalk two survivors at once since you can down 1 and chase the other, but it would be better to try to 99% both and pop 1 leaving the other to be popped later. No real reason to run this since unlike Myers you are picking a single survivor at a time to expose instead of an entire time.

Reusable Cinch Straps, Leather Knife Sheath, Drop-Leg Knife Steath (Movement speed when crouched): One of his only addons that gives him benefit when not in night shroud. Crouching is useful at some tiles since you can break LoS and get a hit you otherwise couldn't get. These addons do help for those situations. Drop-Leg is an 8.4% increase and Leather Sheath is 5.6% so together you get a 14% boost and his base crouch movement is 90% so you can move faster than survivors while crouched. The situations these addons are useful in are niche but at least can be worth running.

Marked Map, Victim's Detailed Routine (Increase Killer Instinct duration when revealed): Useless. You have enough time to figure out where the survivor that revealed you is at base. Granted sometimes Killer Instinct be buggy and you don't actually see the notification because the survivor is too close to you.

Victim's Detailed Routine, Driver's License (Reduce Range survivors can reavel Ghostface): Together you can turn the 32m range that survivors can reveal Ghostface into 20m range. Not an insignificant reduction, but you should be trying to reduce the ability for survivors to even reveal you by not standing out in the open in first place. Ultimately good ghostfaces don't need these addons, because they are putting themselves into situations where they can be revealed.

Ghostface Caught on Tape (Faster Lean Stalk, Slower Non Lean Stalk): Lean stalking goes from 2.5 to 1.5 seconds, Non Lean Stalking goes from 5 to 5.75. It's better than the faster non lean stalking addons since you want to lean stalk survivors to 99% and almost halfing the time it takes to lean stalk is certainly good. I don't think I've ever been in a situation where I thought "man I wish I lean stalked a bit faster". I would say it's okay, certainly better than his other addons.

Outdoor Security Camera (Aura reveal when you down a marked survivor): Probably his next best addon after power recovery. Ghostface can struggle to make good use of Infectious Fright since if he downs a survivor while undetectable no one will scream. This addon allows him to get a sense of where survivors are after downing a marked survivor. Now it is all survivors outside of his TR so if you down a marked survivor while not undetectable you won't see the auras of nearby survivors. But since survivors aren't going to jump in lockers to avoid Security Cam aura reading if you see 2 auras and not 3 then you can assume the last survivor is nearby.

So basically half of his addons are absolutely useless from the start. This leaves us his two iri addons, movement speed when crouched, and faster non leaning stalk as other addon options you would want to run. Of the remaining options only crouched movement and his iri addons are viable options to replace recovery time since they actually do something useful to how you play Ghostface.

At best you might see some Ghostface use an iri addon with chewed pen or Ghostface with double crouch addons, but most Ghostfaces are still going to use double recovery, because it's simply far better than the alternatives.
