I don't know. She's nerfed even from Brawl where she was bottom tier. It's hard to describe what happened to her. She's just broken.
Would you describe yourself as a Zelda main? For an outline, here's some stuff we discovered (subject to change as everything about the demos and we learn more stuff about her)
+ nair buff, more hitsun and less chance of escaping, can combo into utilt on big characters like bowser (don't know if it works on small)
+ naryu's seem to have less recovery lag and have a bigger hitbox
+ FW is a really powerful kill move, capable of killing in the low 30% on lightweights. Also much faster.
+ dash attack combos into itself at low percents, has more priority, has a 'sweetspot'
+ dspecial can serve as meatshield, now lots of people have been saying it sucks, but I think it's just way too early. We did see a 2 sec charge phantom really batter a shield, might serve as a nice way of whittling it down from a safe range (considering it has less recovery lag than din's)
+ usmash pulls in characters and has a faster animation, giving less chance to DI and SDI
+ overall system changes is good for her, as she has lots of multihit moves
+/- uair seems faster but has way less knockback, may serve as a combo move
+/- utilt no longer kill move, but can combo into itself possibly
- dtilt now longer stuns
- dsmash has less range, though it's still very fast and safe
- din's fire has a 'sweetspot' but has way less range and it's hitbox isn't as deceptive, so whiffing and sourspots seem like their going to happen more often
But yeah, seems buffed to me overall.
