And when you start using the same mechanics to do everything, even if you call it something different, none of the choices actually feel different. That was a big criticism of 4e with its hyper symmetrical design.
The problem you're dismissing is that both the fiction and the mechanics are not being satisfied by taking the mechanics for spellcasting and calling it something else just because you don't want to think about it and want all of us that want something more than that to shut up.
It is curious to be so vehemently against someone making an assertion and yet also make one just as all encompassing and assumptive, as though you're not doing the exact thing, except sans any supporting arguments or even evidence.
Ive elaborated on my ideas and why I think them, and what I believe the effects are and what I have observed the effects to be.
Ive come to this table with more than just an assertion that people "like" what they already have.
Anectdotally, I can honestly say Ive never met someone online or in real life that thinks 5e's Skill system is desirable over literally anything with more heft to it.
