That would lead to skill bloat. While arguably more realistic, it would also be overwhelming. For looking at tables I recommend Excel. How’s foraging different from herbalism for example? How’s a motor-driven blade defense platform related to a snare trap. A little shoehorned, eh? Skills should exist when a necessity for them develops from existing mechanics. I’ve made a rather strong point that current mechancis do not justify trapping as a separate skill and it would be even beneficial to split it among other existing skills.
Let’s get more practical. You play as an explosives expert. What are your skills? Trapping? Do explosives experts get training in snaring small game? Using beartraps? Are they taught how to weld together electronic components to create makeshift blade dissectors?
You play as a survivalist - a concrete career path nowadays. Do survivalists learn and make YT videos about how to place, disarm and craft landmines to hunt small game with?
Now lets get even more logical. You have tons of landmines. Used countless grenades, launchers etc. started as a military vet. But you can’t use the landmines because you never snared a squirrel. Makes perfect sense, eh?
Now you are a highly skilled mechanic. You can fabricate anything. You could use your skill to prepare defenses at your base… oh wait. No. You can’t weld a blade trap together, you never snared a squirrel. After all, mechanics are pacifists, they are bound by holy oath to never use their skills destructively.
And again… you pick a book titled “survival” at your local library. What do you find inside? Shelter. Edible and medicinal local plants. Primitive weapons. Starting fire. Snares and fish traps. You know, all things you’d like to know when trying to survive away from civilization.
You pick up a military explosives manual. What’s inside? Snares?
A welding/mechanics book about dangerous machines and staying safe around them. Can’t read it because you skipped the snares class?
Let me do a little TL:DR -
Launchers - so little use, it’s pointless. Rename to explosives, add grenades, landmines = perfect!
Survival - add snares, beartraps = Less pointless, perfect!
Fabrication - give Bob the Builder an ability to use his skills for defense = perfect!
Traps - snares, landmines and giant indiana jones blades shoehorned together? = Illogical!! Booo!!
