The idea or pacifying and even having ememies eventually be able to fight for you is very cool - but the implementation has several Problems.
1. Highly unreliable, even wth very high charisma and luck everytime you attempt to pacify it's still a dice roll. The time it takes to attempt to pacify wastes precious moments as the enemy is closing in or already inflicting damage.
2. Redundancy - these are 4 perks that work almost exactly the same way and each require 3 perk points to reach max level.
3. Level one of each of these is practically useless. Just pacifying the enemy for them to sit there is pretty meh. Especially considering that to unlock these perks (except animal friend) you need a pretty high SPECIAL level.
4. There's also issues with companions/NPCs attacking pacified creatures etc and some bugs with highlighting (power armor helmet mod and night vision) causing issues with it. May have been fixed.
5. Pacify does not work with Melee characters.
6. Successfully pacifying grants no XP.
I feel like when they started developing these perks they decided it could be too OP and just made them completely lackluster. Then went over to the luck skill tree and completely blew the idea of OP out of the water. If luck can be so OP as a killing machine why can't charisma be as equally OP at pacification?
I'm not sure what the changes need to be but j would really like if they went back in and reworked these perks. XP gain and more usefulness at rank 1 would be a good start. Also, maybe have them each work a bit differently?
And ghoulish should have increased chance to have ghouls become friendly with each rank - not just at rank 3.
