These are the five who emerged.
Though i noted very high survivability with Rosalina and Palutena, they did not perform well in free-for-all terms (low KO power).
Palutena has more promise than Rosa in that regard.
Mr Game and Watch is out, he was actually one of the worst assessed. God knows what Sakurai did to him, but he doesn't work much anymore. Bowser is insane, Pac-Man is surprising, Dedede, Ike, and Kirby retain goodly amounts of usefulness from Brawl (though Dedede's changed a fair bit, his changes don't seem to hobble him, unlike what i initially feared).
Monster Hunter: pissing me off since 2010.
