Franchise Reboot Theorycraft

im proposing a new idea for balancing which types should be in a game to whomever works on the games. It's definitely an interesting idea is it not? Thinking along the lines of gen 1 and gen 5 and maybe this could be a concept for gen 15. Though gen 5 made psychic types weaker they weren't the most common type and weakest. But in a new flagship for a new generation example could you want another generation composed of over 90% new Pokemon?
