"The aim is to role play and not rule play"
There have been "diceless" systems around for a while. I agree in general terms though - my own homebrew system has stats/saving throws/hit chances etc for the basics of the characters but I prefer the players to flesh their creations out. It makes it more fun for me for one thing. My ex gf hated most RPGs but quite liked mine as it was character focused not a number cruncher.
D&D 5 is very much D&D-lite as far as I can see - quick, simple and very limited.
