See, I'm one of those who had a folder chock full of character concepts I'd built and kitted out without knowing if I'd ever run them; so the folder was a 'so long as I stick with the same GM for a long while, literally any of thees concepts can be wheeled out and minimally retooled to fit whatever we're doing'. I don't feel half the same urge to do that for 5e because of what you call the 'barely any choices to make' issue.
