Who the hell would be unhappy BESIDES d3 mains wanting to use a broken move and 95% of the d3 mains here are pro-ban.
First of all, 95% of D3 mains are NOT pro-ban. Stop pulling random numbers out of your butt.
Secondly...
1. Wario mains would be unhappy. They can still be infinited by D3 via grab release. Wario can still be infinited by who knows how many characters, and killed out of grab release from others. Why let Mario and Samus and Luigi run free, while poor Wario still gets ***** from grab releases? One of his worst matchups is Yoshi, for Heaven's sake.
2. Donkey Kong/Bowser players would be unhappy. Now, they are free to roam about and are free from the worry of the 9-1 matchup against Dedede. NOW, they have to deal with Wario. Wario has a Dthrow chaingrab to kill percent which can be combo'd into a Forward Smash for the kill. Why haven't you banned Wario's Dthrow chaingrab yet?
3. Fox mains would be unhappy. Fox still gets Dsmash-chained by Zamus and Chaingrabbed from 0-Death by Pikachu. Why the hell haven't you banned these two 0-deaths yet?
4. Wolf/Anyone who can't recover from a Falco Chainspike would be unhappy. Why the hell are D3's victims allowed to run free, while Falco still ***** the crap out of these poor souls cursed with a bad recovery and susceptibility to chaingrabs?
5. Anyone with a competitive mindset who was around to play Melee would be unhappy. Sheik chaingrabbed 0-Death over half the cast, yet it was allowed. Jigglypuff 0-Deathed Fox. Falcon 0-Deathed Fox. Marth 0-Deathed Fox. All of these 0-Deaths on Fox were allowed and Fox still became the #1 character, because he 0-Deathed EVERYONE. Ice Climbers 0-Deathed everyone with wobbling, yet for some odd, strange reason, Wobbling was allowed at most tournaments. With all of these 0-Deaths, the top 4 characters reigned supreme, and these people knew that, but they banned nothing character-specific aside from things that truly BROKE the game (ICs Freeze Glitch is the only thing that comes to mind). Melee then became one of the most popular fighting games of all time, and every character past Falco on the tier list really didn't matter much in the grand scale of things when it came to who was truly WINNING all of the big, national tournaments. These people know that banning the D3 chain grab is a quick-fix, and will mean absolutely nothing in the grand scheme of things other than being a waste of manpower, a source of various complaints on "Hey! He infinited me!" "What? No I didn't! I took 3 steps!" and just plain being a waste of time to enforce.
TL;DR version: If D3's infinite gets banned, DK will not suddenly begin tearing tournaments a new one, and Mario will not suddenly leap to top tier, as they usually are still plastered down by the other top and high tiers, anyways.
Thats a prime example of why it should be banned.
Because some people can't adapt to the changing metagame and don't like the fact that their character has a matchup in which they shouldn't be using them? Tough buggers for him. Every time a Ness main goes to a tournament, he runs a risk of running into a Marth. Every time a Fox goes to a tournament, he runs the risk of running into a Pikachu. Every time Wolf goes to a tournament, he runs the risk of running into a Falco. Every time Olimar goes to a tournament, he runs the risk of running into a Peach. Every time Samus goes to a tournament, she runs the risk of running into a Lucario. Every time Ripple goes to a tournament, he runs the risk of running into a King Dedede.
And yes its VERY Easy to implement which is why most states in the Atlantic North have them banned no problem. Theres no 5 grab limit either. Its just you cant do it at all.
Tell me this: If there was 5,000 dollars on the line, would you, or would you not take 8 grabs each time and deny each one if it meant you had a better chance to win, or accuse your opponent of using 8 grabs each time if it meant you had a better chance to win? If you say no, you're either a saint, rich, live in a cave, or a horrible, horrible liar.
Can't believe I missed this...
Lol, no.
Well, not for Mario anyways.
I'm not going to go into the matchup myself, but even if it was just a normal chaingrab, it would still be an uphill battle for Mario. Mario would not suddenly **** Dedede if the infinite was banned. Luigi might, since he cannot be CG'd normally, but Mario would not.
I used to play Brawl every day as a dedicated DK main. Now I barely ever play, and a large part of it has to do with this infinite. Should any of you give a **** if I still play Brawl? Hell no. Just putting in my two cents: the infinite is the stupidest, brokenest bull**** in the universe and if you support its use you should put your face in a waffle iron.
If you're going to simply give up less than a year into the game, and not even TRY to get around this bad matchup by choosing a secondary, or practicing avoiding a D3 grab, then you deserve to quit. Simple as that. We don't need quitters like you in the Smash metagame, as harsh as that sounds.
