Chronobound, why are you so wraped up in series getting the representation they deserve? That is a completely subjective idea, you could believe mario deserves 5 reps, whereas i could believe they deserve somethin like 8. Not to mention you have to take into account character viability, a series like metroid which only has one real main character,samus, can't have this rep by popularity that you propose, because simply metroid doesn't have many characters to represnt it. Where as the mario franchise has a few viable characters nintendo can work with to put in smash, toad, bowser jr, waluigi, daisy,etc. i could list more. Going back to metroid you have, maybe Dark Samus, and sylux to work with. Ridley they obviously felt they couldn't make it work so that widdles it down even more. So when you strike ideas like Kystal Claus or whoever because there franchise doesn't deserve it, think about that maybe that doesn't matter as much as being able to make characters work.
And brawl is a total mochary of your idea anyway, Kirby has 3 reps, sf has 3, mother has 2 where Dk on your numbers is 4th and they only have 2. SO clerly nintendo cares little about representation as they do about using characters with a fan base and characters that can be made with viable movesets.
To me representation should have little to do with the selected characters for smash. The only time it should be mentioned is if someone goes overboard on a series like stating ssb4 should have fox falco wolf leon panther krystal, pigma, peppy, slippy. Only in this instance would i say representation matters, butwhen people suggest a 1 character increase i really don't think its to much to ask, i.e krystal, claus,
