Sorta sucks she didn't get her own moveset, but if she was originally played as a Marth alt, I will be thankful enough for her being her own character slot and having slightly different characteristics (hopefully it's not just the height and no tipper though). I wouldn't mind her being a Marth alt (better than not being in the game) but being slightly different will be interesting (I'm a Marth user) so it gives me more choices :D
It's a pity they didn't have enough time to create an entirely new moveset (or even a semi-clone), because I was confident Sakurai would be able to make a different, unique sword fighter apart from Marth and Ike.
Oh well, perhaps if she sticks around for SSB5 and gets more appearances/games til then, she can get her own moveset some day
