I have a few ideas for perks, bouncing off of what VictorNoctarius suggested and also just based off some of your own perks.
These ones are opt-in ones similar to Wild Wasteland from New Vegas, that add a unique gameplay experience that some won't like, but others will, which is why it's optional. This can also help tweak a survival experience without needing players to choose Survival mode to have a fun, survival-based experience.
Schizophrenic I/II/III:
I: Hear enemies within a certain range, whether it be ghoul growls or the crawls of radroaches, with a low chance of occurring.
II: Hear enemies more often, and much closer. This time you can also hear raiders/mutants/human enemies talking alongside the previous enemies listed.
III: Along with the previous effects, enemy's will show up on your radar HUD, even if they don't exist. When players go into the vicinity of where the HUD is telling them an enemy is, it'll dissapear from their HUD. NPC's will also appear as special encounters, and their dialogue would be vague/mysterious, only for that NPC to dissapear/fade right in front of the player's eyes. They could be traders or just wandering settlers. Can also potentially hear nuclear sirens going off and nukes going off in the distance, but would simply be imaginary.
Not Exactly A Dud I:
I: It's a nuclear wasteland, surely some of them never went off? It doesn't mean they aren't dangerous! Upon taking this perk, a small amount of nukes will spawn in certain locations around the wasteland as special encounters and can go off at any time. They have an increased chance of going off if the player is in/around a nearby map cell. These will respawn every 2 weeks in-game time in a new, random location in the wasteland.
Misty Eyed I/II:
I: Fog/Radiation Storm's are 50% thicker, making it harder to see when those occur.
II: Fog/Radiation Storm's are 75% thicker, making it even harder to see when those occur.
These next ones are just general perk ideas that effect gameplay/combat and just some mechanics in general.
Unclean I/II/II:
I: When enemies are within a certain vicinity of you and are alerted, they will slowly take rad damage (if affected by rad damage) over time.
II: The speed at which enemies take damage by this perk is increased.
III: The damage this perk gives to enemies is increased.
How about Paranoid Schizophrenia, as in there are enemy voices playing from time to time without actual enemies being near you. As a result, you become hyper-aware of your surroundings, marking all enemies red like the HUD mod does?
Also, hyper-specific weapon perks, like the one for the minigun. Things like the Broadsider, Junk Jet or Tesla Rifle could use that quite well. Or make them specific like "scoped laser weapon", "automatic plasma weapon", "electrified melee weapon" etc...
I have not tried the "block bullets with melee" perk as of yet, BUT if it doesn't already do that, you could give it a 2nd level where it actually refelcts the shots back on the attacker. Maybe let it use up AP real quick though, and have Perception 10 as additional requirement.
Maybe something like, whenever you kill an enemy with a melee weapon, surrounding enemies are frightened for 3-5 seconds When entering combat, spawn a pack of friendly wild mongrels, with 2 upgrades being Yao Guai and then Deathclaw? If yes, the same perk but with insects: bloatflies/bloodbugs/radscorpions?
I would love to see the Slayer perk or Piercing Strike return, or honestly, any variety of perks for Unarmed players. Fallout 4 is lacking extremely in that area, from weapon variety to perks especially.
id like to see a perk that gives my companion infinte ammo for whatever weapons there holding. and another perk that requires that perk that gives them unbreakable power armor.
