So, after messing around with Zelda some more against a friend of mine (instead of against cpu's in training mode) I've noticed a few subtle things. Dtilt seems to have a small KB growth decrease. Hitting people with dtilt when they are around 100% used to send them up too high to hit them with a FH fair, now, it seems that it sends them lower allowing for the FH fair to hit them though it still requires some reading on our part to hit that fair.
I also noticed that the hitbox for fair (not sure about bair) sweetspot had extended very slightly. I hit my friend when my foot wasn't even touching him but it sweetspotted and killed. The changes to fsmash and usmash are wonderful. I caught my friend in usmash as he was jumping over my head as speed Shulk and I caught him on the very edge of usmash's hitbox and he got sucked into the entirety of the attack. Same as fsmash. I caught him in the air with a fsmash and he still got sucked into it so, while grounded opponents get stuck easier, so do aerial opponents.
The changes to phantom are hardly noticeable but I'll take ~3 frames of endlag shaved off. I'm not complaining. These all seem like buffs to me. Subtle buffs but buffs nontheless. No change to landing lag as far as I can tell unfortunately. I can't find any nerfs so I'm not gonna complain about that either.
