Thor you don't understand Metaknight's priority. It can't even be altered because he's hardcoded to outprioritize the game. Even in Minus, Vbrawl MK would not be outprioritized.
I should stop using the word priority entirely, because people don't understand what it really means. Do yo understand what priority is? This isn't a facetious question but a real concern. Here's what I understand the term priority to mean.
There are r3 types of priority: normal/aerial/transcendant which is directly related to the law of high/low priority which both have zero relationship to range [and which people mistake for priority - often along with hitbox placement]. MK having transcendent priority on most of his stuff has already been shown to be a drawback (TL arrows, Link any projectile, he can't clank them except with his DA), and his range isn't really as helpful in a game where everyone else has landing lag matched to his [and at last check, Marth fair outranges his own fair, much as Pikachu fsmash outranges his ftilt and I believe fsmash as well]. He'd be outprioritized because his non-transcendent hitboxes (namely nado) are much easier to outprioritze via the law of high and low priority [attack buffs], so it would be much easier for certain attacks to kick him out of nado (Turnips, bombs I believe would work, some other grounded normals (I think Falcon ftilt would have the strength to hit him out of nado now).
As for my claim about MUs: Falco can now do everything he could in vBrawl to hurt MK, except he's not going to get gimped and he can teleport in - he also has a stronger fsmash, stronger usmash, and a MUCH better fair and reflector which means unlike in vBrawl [though fair still is bad for trying to attack someone who also has hitboxes out], which means he's able to safely be in the air facing forward against MK and KO him faster. He can also actually try to gimp MK much more safely now, and he can also use all kinds of tricks with Phantasm. It wouldn't be a fair fight, for vBrawl MK. At BEST it would be even, because MK would have a strong combo game, but Falco still would be able to always be able to mash jump if they aren't frame-perfect (true) combos, and he has his own damage-racking tools that already make him a solid character in Minus suited well to beat MK.
I've also explained Pikachu, who has buffs on certain moves and key buffs on t-jolt and thunder that would allow Pikachu to once again beat or go even with vBrawl MK.
Also if people want to do that, when I get back I'll fight someone's vBrawl MK, either ported into Minus (so susceptible to Minus hitstun but otherwise the same) or in vBrawl (where I won't be using characters who are buffed up and he would be the best character).
Thor don't get mad no one takes your opinions seriously when you present them all as certain facts and you've given us no reason to trust your opinions other than 'i enter vbrawl tournaments'. Link me to a tourney you topped at with real competitive players or otherwise back up your credibility, otherwise your claims of MK being not that bad are gunna get laughed off as they have been already.
If you disagree with how I think the MU would play out, tell me what's wrong with the pictures I paint.
Considering you've given me nothing either, I can see why this will go nowhere. But I've said it above and I'll say it again - whenever I can finally get my Wii back (bleh parents not letting me bring it to college right away), I'll fight anyone's vBrawl MK, in vBrawl or in Minus.
Also, link me to a tourney you topped at with real competitive players or otherwise back up your Brawl creds, otherwise your claims of MK being so bad I'm going to keep laughing off like I have already, while continuing to cite facts and theory-craft on the actual MU instead of axiomatically reaffirming "BUT IT'S VBRAWL MK HE'S SOOOO SCARY!!!" Because none of you (except Kien, who I'm sort of assuming slings around priority as a misnomer like so many other people, but thanks because I may have misjudged) have provided real reasons except "HE CAN ZERO-DEATH!" So can Ganondorf, Captain Falcon, ROB, Jiggs, and other Minus characters, but people don't point them out. And I think debating the theory (or playing it out, if I only had a Wii) is much better than saying "I'm M2K so I'm right!" I've pointed out why the MUs would have improved from Brawl - if you believe he would still dominate, explain to me why they haven't improved or would now be worse.
I live in MN, we don't have much in the way of Brawl competition and no one before I left cared to record our Brawl stuff, but I have taken a game or two off the top MK in our PR and took 5th at the one tournament I could make (I could find the SWF results - me beating the guy was in friendlies though so it wouldn't help much).
Oh wait I'm not allowed to hold people to the same standards they try to hold me, is that it? Well I've made various claims to support my stance, you are just like "MK is hard" - if he's really so bad [strong], then surely you can explain to me in no uncertain terms why my theorycraft is wrong and how the MU actually looks?
