Baffled I haven't seen anyone mention Kid Icarus Warriors when that had always been the most talked about before in these discussions.

I think what hurts FEW the most outside of its garbage roster is thatmost FE characters don't really have powers which limited movesets a lot. Compare Link's blade beams, Zelda's light arrows and Impa's water shenanigans to Chrom throwing a javelin really hard or Marth stabbing quickly.
In KI, pretty much every character has some sort of power to make use of in their movesets and even ones that don't(such as the Pits) can make use of weapons that do.
And of course, the characters. KI's main cast is basically Pit, Palutena, Dark Pit, Medusa, Hades and Viridi, but there's a bunch of more smaller characters in Uprising that would make great playable ones such as Magnus, Phosphora and Pandora. It has a well-enough estabilished main cast while also allowing for more unique and out there picks.
If I had to make a KIW roster without any clones(and also assuming no character has multiple weapons ala HW):
-Pit
-Dark Pit
-Palutena
-Viridi
-Magnus
-Phosphora
-Pyrrhon
-Medusa
-Hades
-Thanatos
-Pandora
-Poseidon
-Dyntos
-The Little Girl and the Dog
