Really disappointed in the final smashes. They kept all the clone ones the same and they changed a few of my favorite. Kirby's new one is a lot more powerful but I miss spawning a ton of items with the old one. I also noticed that every crate/barrel/party ball never has more than 2 items in it. I loved King DeDeDe's old final smash as well but that obviously got changed because of the 3DS hardware.
I like what they did for Pit's and Charizard's, but yeah they could have revamped a few more of them. I really liked Kirby's old one for the Super Star nostalgia... it also felt harder to dodge.
