Eh, I didn't mind Smash 4's roster handling for the most part. I liked seeing Rosalina, DEFINITELY Megaman, Pac-Man, Palutena and even Dark Pit (though ideally he would have had a different moveset), Lucina and kinda Robin (Chrom would have been better but atleast Robin brought a unique moveset), both Little Mac and Duck hunt made for cool retro reps, Shulk was great, I pretty much liked every DLC inclusion, Animal Crossing was a sensible inclusion...
Obviously some characters I wanted didn't make it into Smash 4, though what characters DID make it into Smash 4 I was still quite satisfied with.
