I fight a battle. I level up. Now I'm suddenly better at crafting (because I decided so), even though I only won a fight and completed some quests, which should logically not affect my crafting skills.
I have to ask again, how is different to most of the abilities, killing a rat and gaining bartering makes perfect sense to you?
That lower response... Now THAT'S a straw man.
Not really, you are arguing that is better because is like real life, it follow the same logic
p>q
q>r
ergo
p>r
Where q is like real life, r is better and p would be crafting as its own skill or non-magic, the premise you introduced lead both to being better
