KO setups are easy for Zelda in this game. As I stated SEVERAL TIMES, you can legitimately land trap people with Din's. Throw it at them when they're a little bit above something like short hop height or something, and if they airdodge, you literally have enough time to F-smash. This didn't work in any other Smash games except on like...Bowser in Brawl, who had absolutely no landing options. Even if for some reason they have an aerial that might clank with it, that's also usually punishable either by slightly altering the timing you release Din's, or during the end lag frames of their move. Din's also can control the way your opponent recovers, which gives you more options for edgeguarding. Yes, that existed in Brawl, but edgeguarding with Zelda previously was near-suicide to attempt due to her Up-B being way worse for recovery. Even the simple fact that you can edgeguard safely is massive.
Edge trapping is also insanely strong in this game. If you aren't getting free kills from it now with a character like Zelda who has STRONG pokes and long ranged lingering hitboxes, you are missing out on a huge part of the character, because you can't edge stall your way out of edge traps in this game. Then there's the universal option of edge stealing which is relatively unexplored. Currently, it makes Ganondorf not a 100% complete lost cause when it gives him more ways to guarantee you die when he finally gets you offstage. Zelda on paper has a stronger B-air than Ganondorf, so checking to see if she can hit people with it after edge steals is important.
Finally, against people that try to land further away from you, the fact Faores is a KO option means you can cover landings at massive ranges even though your run speed is relatively slow. Also gives you options to read B-reversals and punish accordingly. Point being, Zelda can most definitely cover the necessary options to trap people into KOs in this game, which was not the case previously.
Yes, if you always knew where Zelda was going to teleport, Faores would be terrible. That's CLEARLY not how it works, and that is clearly why right now, Faores is a good move, because your opponent needs to react differently to punish you for teleporting different directions. Gets you out of juggle traps and edge traps easily. Then there's using it for land trapping, which you COULD do in Brawl, but the reward was nearly nonexistent making Zelda not scary at long range.
Yes, there's some really fast characters who can wait out the total duration of the move and punish you reactively if they weren't already committed to pressuring you. I'm not denying this. So don't throw out the move in neutral against those characters where they're in a position to reactively punish you. That doesn't change that the move is overall very strong for mobility that can get you out of traps and keep your opponent guessing. Zelda is VERY hard to juggle and can escape from edge traps much more easily than other characters BECAUSE Faores exists. Add her HUGE range at which she is able to potentially KO you for simply landing, it's a fantastic move, and denying that is in fact utterly insane.
And again, you never needed to state the obvious "DON'T USE THIS MOVE OFFENSIVELY UNLESS THEY'RE WIDE OPEN". That's ********, and nobody is denying Zelda needs to approach and her approach options are not entirely safe. She DOES have better footsies than before and her options to capitalize on the negative state are MUCH MUCH better than they were previously, due to land/edge mechanics, and due to Faore's Wind being a long distance KO option. Meaning Zelda CAN beat turtling in this game.
Honestly so much of your argument even if the majority of it is factually correct misses the bigger picture and dodges the actual main points that are being argued. That is particularly why you and Aerodrome are intolerable and shouldn't be in the discussions, because you are both equally wrapped up in the wrong irrelevant things. You want to claim I'm set in my opinion? That goes both ways. I will concede you made slightly better points about ways Faores is unsafe to throw out in neutral, but it still is not seeing the larger picture and factoring players understanding beforehand the CORRECT situations to be using options.
And to reiterate, nobody including myself is saying Zelda is top tier, or even likely high tier. She is however a very complete character in this game with good footsies, good survivability, and good KO setups. She IS slightly below average in neutral due to her lack of a safe air approach and low ground mobility, but that isn't unworkable.
