And the corollary, overbuilt min-max character based solely on researching the meta for hours but only rolls good at things they're not built to do

That's actually an intentional mechanic in Monster of the Week. The Mundane gets bonus XP by wandering off on their own and pushing the plot forward by needing to be rescued a la Xander.

I actually like point-buy systems where you get better at what you actually use (like in Morrowind).
I start at average values in everything and see where the story takes my character.
