When I play a crpg, I tend to push as many numbers as I can into intelligence and charisma because I like playing talky characters. Is that minmaxing? I find combat the least interesting part of most games and so I stat out based on that. But I'm still approaching from a mechanics first aspect, and then I come up with a character concept that makes sense with that. Furthermore Josh makes a good point in that video when he says that sometimes if you want to make a flavorful character, you're going to have to fight against the rules to a degree to make your character do stuff they aren't really built to do.
I feel like at least on these forums people don't seem to differentiate between minmaxing and just caring about the numbers. I don't want my character to be bad at the things they're supposed to be good at. My first playthrough is going to be a pact of the blade warlock. Before Larian's changes that would have been an unoptimised choice by default, so I would have had to really put thought and effort into making her work and be good. So yeah, minmaxing is a thing, but not everyone who doesn't close their eyes and ignore their stat spread is one.
