I'm not the one getting aggressive over others for thinking a mid-tier that can be dealt with is, in fact, a mid-tier that can be dealt with, but sure, let's point out why everything you said was baseless:
-tethering recovery is overrated. it's even worse for a character that has to rely only on it, whereas at least link has a safe up-b to deal with. stick to the ledge, tethers can only jump when you hog it, and punish. basic stuff, I'm still sort of amazed people don't know this yet (or know how to edgeguard good recoveries in general)
-"really good against big characters" means nothing, because big bodies consist of about five to six characters, and this is a game with over forty, nearly reaching fifty. certainly a nice matchup quirk, but not much else
-the upb has a hilariously badly-placed hitbox, and actually has 20 frames of startup, if you get hit by it that is damn well your own fault
-dair does not spike, that's a flat-out lie, learn to mash out of meteors
and then the rest of your points are either belittling the intelligence of everyone involved, or hoping that maybe if you scream "she's invincible" for long enough nobody would pay attention to the incorrect things you've said.
you expect people to take you seriously, when you can't even bother to look up any of the data and research THAT'S IN THE BOARD YOU ORIGINALLY COMPLAINED IN which I found within a minute of looking. don't be surprised when nobody takes you seriously
