“It’s probably Matt Mercer’s fault.”
These guides exist for a reason
I think that reason is that previous iterations of the game were complex enough that the guides were helpful, and now there's a tradition.
I seriously wonder how many players read them, and suspect (although haven't tried to demonstrate) that it's a tiny fraction of the number of people on D&D Beyond, which is where we get our data about race:class choices.
