Alright gorls, I feel like expressing my thoughts and theories here to hopefully rekindle some hope to your tortured souls.
I think Zelda will get significant buffs within the next few patches. The balance team has a lot of work to do and I can only assume that they have sparse manpower due to the company working on other titles, moving away from smash because sakurai said so, and the mystery of smash for NX. Out of the 15,000+ matchups in existence, the team has to consider balance against a wide range of opponents for a character. Then you must factor in DLC characters. Suddenly the team has to stop tinkering with the already "finished" characters and work on things pertinent to their new deadline.
Now you have fire emblem characters being sent to the forefront to make sure they are not made irrelevant in the wake of the new character, oh and Shiek and ZSS have been stomping everything afirst, everyone begs for nerfs all over the social media so gotta do something there as well. Your time to check the status of a character with a diminutive playerbase is limited drastically. You need to focus on the important things first; such as making sure Marth mains don't ragequit from lack of fun. And whatever falco buffs you finished during your lunch breaks can be stuffed in the patch as well. Good enough for now, now we have time for the first time in a long time.
Time to look at the bottom of the barrel.
I think that what is happening isn't a lack of caring or communication, they have been doing a fantastic job cleaning up messes and listening to the playerbase for the most part. But that's just what it is, a job; there are deadlines and issues that take priority and there is (probably) only one team in charge of it.
I have no doubt that if a large portion of the playerbase had direct input of could help take the load off that the game would balance much faster, but as it is things are going to take time.
Zelda probably has a laundry list of changes not quite ready to be implemented. She is a terrible character and will require a LOT of work to get working right, way more than most characters. So much, that it could very well be a waste of time to rework her when there are three new characters that need to be ready in a month. Deadlines are real gorls.
Gorls, Zelda hasn't been forgotten. She is just going through some development hell. If we get any more patches you can bet that she will get substantial support. Most likely not enough to be A+ teir, but certainly something to make us feel better and perhaps we will start losing to players instead of their mains.
Stay sassy, hope will never die.
