There is much here that I agree with.
I am of the opinion that 5.x character generation is a sub-system that requires computer software.
I want a tabletop game. With math rocks.
Coming back to the game (from 3.0/d20) after a twenty year absence, my reaction to the subclasses of 5.x was
Wizard
Treant
Fighter, am I being railroaded during character creation?!
Give this aging grognard some recognizable
Core / Iconic / Legacy class(es) so I can play with the younger folks and their newer edition! I don't want to have to put in unenjoyable
work just to play a
game.
Obligatory exclaimation: "Get off my lawn!"
