I think Wolf is an easy character that will fall to the ass end of top tier or maybe even high tier outright (esp. if he gets nerfed, which is likely with how many people are crying for it) as the meta develops and a lot of people are way too quick to defend his flaws. All the frame data in the world doesn't do jack when you get outspaced
Wolf doesn't even have super fantastic top notch kill power either, once he racks up heavy percent on you he's usually relegated to fishing for BAirs in neutral or going for grabs / USmash.. all of his popular kill options aren't being confirmed / combo'd into and require reads / punishes. One of his throws (I cannot recall) confirms into side B, which can cause all sorts of **** like him instastocking you at 40% (the range for this is around 28-45% depending on weight) if he throws you offstage (which is gonna kill him too after you die, but if he's up a stock or you're on your last it doesn't matter) or if onstage, stage spike you so hard you'll likely not be able to land again before he kills you. That's his best early kill option, and that's really not that fantastic compared to what other characters have. He has the DThrow > Side B option still at later percents, but this one doesn't give you the option to kill NEARLY as early as the other one, I believe that one may be DThrow too? Or perhaps BThrow, I forgot.
Full waft can kill at 0 and nobody on the roster is surviving it past 40-50% or so anywhere on the stage, and with Wario hitting like a sack of bricks a stray dash attack in neutral is all he needs before he goes for the UTilt combo confirm as the combo will rack up the rest of the needed %, then your stock is invalidated. It's one of the most busted kill options in the game, and I love it. I wouldn't ever advocate its nerf, I'm just using it as an example of how other characters have kill options leagues ahead of what Wolf has, and that's just one of several examples.
I know the appeal of Wolf is the package, not the individual parts, and you can't deny he's very well rounded in a lot of areas. That said, he's not perfect. His recovery is total ass. He eats combos harder than some other characters due to his fall speed. He doesn't really have any sort of guaranteed way to kill you off of a stray / weak hit in neutral like other characters do, he's usually stuck fishing for BAirs or punishes. Neutral airdodges really **** up his UAir if timed well because it doesn't linger long. Same with FAir. Wolf has piss range outside of his specials. Wolf has really bad disadvantage state in some MU's. Wolf has really bad neutral options in some MU's. Etc.. Etc..
Wolf is a very good character, right now no doubt somewhere on top tier. Will that last? I doubt it, he'll fall some. I'm not saying he's bottoming out into mid-tier or anything, but people are too quick to look past his flaws when tacking him onto the #1 spot of tier lists and asking for nerfs.
