*sigh*
Even I'm beginning to lose hope...
If you go and look through the comments, you'll see a lot of people adding to the Zelda discussion, and he admits several times to not having using a lot of her moves, or not having noticed so and so changes - I doubt he's a very big Zelda player, and I doubt he took a lot of time with her comparatively to some others.
Her smash attacks in the demo honestly look about on-par with Brawl's, in terms of knockback/killing power. I went into training and made a Fox dummy, then changed his % to the percentages at which she was hitting him with various attacks in the Zelda vs. Fox match video, and her smashes were all doing around the same knockback from the same distances - obviously, there's gonna be system changes and such, but they still looked around the same - and their knockback is fairly solid in Brawl, so I don't think that's a big issue for her still. Her dash attack, on the other hand, was greatly increased in terms of knockback scaling, able to kill very respectably. It looked like her ftilt, utilt, and uair all had lowered overall knockback, on the other hand - contrary to his statement that uair has more knockback. It also comes out quite a bit faster. We've also gotta think - "does decreasing the knockback on her tilts and aerials actually hurt Zelda in the long run?" - since she is a character who's problem is not a lack of moves with strong enough knockback to kill, but rather, one of her problems is that her moves have
too much knockback, making it impossible for her to chain moves and rack damage. Decreasing the knockback and increasing the speed of some of her moves allows her to more easily get potential combos off. I'm not so sure that these moves having decreased knockback is truly going to be a nerf to her, overall.
That's in addition to the fact that her Smash attacks are now less likely to be DI'd out of (they appear to be slightly quicker to end, and apparent system changes have fairly significantly lowered the imapct of SDI) - and therefore more likely to connect with her strong final hitboxes; her Farore's Wind teleport is much faster and ends in a
very strong kill move with decent damage (12-13%); she has a new and unexplored special whose intricacies - weaknesses and strengths alike - won't fully be understood until we've had some time with her; and I've heard it said her sweetspotted aerials are easier to hit with (particularly dair, which I've heard does more when
not sweetspotted now as well).
She's a character who needs a lot, and I won't be
surprised if she still can't rise out of the lower portions of the tier list, but I think she has a lot more subtle changes up her... gloves(?) that we need to fully realize before we make any real judgement about her.
And who knows? By the time the game comes out (next month in Japan!) we may be seeing a Zelda who is ten times
better than demo Zelda, or potentially even ten times
worse. We also don't know how she fares in comparison to the cast who wasn't available in the demo, which was likely less than 1/3 of the total roster if the roster ends up being around 50 characters!
