Jokes aside, I do think Ramlethal's range is being overplayed here. Her max range is more comparable to Sephiroth, and while that's still redonkulous, very few of her attacks seem to be full swings where she really leans into it, so her range would probably be more comparable to normal swordfighter's on average.
Also, the dynamic of a swordfighter who can use her swords as dangerous projectiles at the cost of her disjoints sounds incredibly interesting, especially for Super Smash Bros.
EDIT: And it would be different from Pyra in that it would be the focus of her design, and that she can actually do stuff without her swords.
