I don't see what the big deal with the transformation is. If Zelda lands a Fair, you have time to change. If Sheik lands a Fair, you have time to change. The speed could be increased for sure, but that is not the issue and I will not bring it up again.
A nerfed Sheik would be nice. Mainly just the way her Fair and throws are too easy. If the throw mechanics allow people to escape faster (which they can as of E4A when Pika and Mario could chain only Bowser and only maybe three times because they gained mobility quickly.) then that would be enough to level out Sheik.
If her Fair is nerfed even slightly, I still say problem solved, so no more *****ing about that...
Balancing the characters eh? Sheik was good, but Zelda wasn't exactly horrible. They are meant to work together but not be similar in any way.
Gameplan
Sheik: Fast, effective aerials and good tilts, dash-attack and throws for set-ups in the air. Few finishers, poor recovery, lacks range.
Zelda: Strong, many effective finishers and good priority on tilts, smashs and aerials. Imobile, slow attacks, lacks set-ups.
Sheik and Zelda can be used together plenty. There is in fact
ONE thing that would have balanced them out in melee. This
ONE thing would have made them equal but at the same time, created a super character for the way they could be used together, yet apart. They were built to be like Ganon and Fox in one character right? Now that would be broken and it is obvious to all of us that with the ability to switch between those two would be godly. That is because they are both great characters on their own. But if you combined the likes of Bowser and Pichu, then people would no doubt use both accordingly.
we have the Fox but lack the Ganon. The only thing Zelda would need buffed is priority on her attacks. Speed buff? Overdone and it is not in her character, plus that's why Sheik is effective. Something else, Strength? Everything she does is lethal!!! She can hit people fine with them too. But they can hit her just as easily.
She needs more priority. If her forward smash had this much range \/
in melee, she would've been used just as much as Sheik because she really would have something that Sheik severely lacks in. That would seperate them. Sheik is offensive with her speed and defensive with it at the same time. Zelda is offensive with her lethal hits and can be defensive with them at then same time...if the character has to actually concern themselves with avoiding them...
Oh look!!!!!!!
Zeldas FSmash has a disjointed hitbox beyond her fingers nails?!?!
Problem solved, and no matter how good Sheik or Zelda are, you would need both to use them/HER to full potential. Pichu sucks and Bowser sucks. Together, they wouldn't be AS bad, that's true even if it helps just a little little wee bit!
