On anti-spacie tools:
Simply because of the spacie's fast falling nature causing them to be easily juggled, chain grabed, and killed, every character ever will have tools against them. They did in Melee too: look through the melee low tier forums and try to find one that doesn't have specific sections on how to zero-death fox or gimp falco easily. When these characters receive tweaks and adjustments to allow for better movement, juggles, and kills in their other matchups, it makes perfect sense that these tools will give even better combos against fast fallers. A move that against Mario will allow for a few follow ups, not always neccesarily true combos, and frametraps/juggles, will be able to net a grab, easy combos, grounded juggles, etc etc against fast fallers. Being susceptible to easy combos and juggles in exchange for fast shhls and combos is just a part of being a fast faller.
Basically I just want to point out that these "anti-spacie tools" are all really just anti-other character tools. Moves that combo a floaty well will no doubt combo a fast faller even better, or at least set up a tech chase. So it is hard to have characters that have very little "anti-spacie" tech that still can go well with other characters.
