I wish I could find Hylian's posts on IC's infinites but they are what convinced me they belong in vBrawl and I feel like a lot of people should read them
Anyways, removing the infinites removes ANY reason to play as them.
Desynching is a gimmick mind game tool that can be turned against you VERY easily. First time you see a desynch you will be amazed as they slowly creep towards you with alternating blizzards. Then there is the point where you realize something. The IC's have poor options. If you can space properly then they have nothing on you. They can desynch aerials, ice blocks, blizzards or whatever move they want but look at where it leaves Nana. Away from Popo. It is great against somebody who doesn't know how to deal with it but a player who knows the matchup can render it basically useless and arguably a bad idea.
Their other CG's? They give them like 20 or 30 percent. Dthrow to Fair will go like 25 percent before the opponent is forced to hit the ground. Dthrow CG offers little percent. Other then that, all they have is their alt throw/hobbling infinites.
Yes, I do understand that Brawl+ has the ability to give them new options. But Brawl+ shouldn't take a characters metagame and throw it away; that gives a bad picture to the game and goes against the idea of it anyways. Wasn't one of the reasons against MAD and HAD in official Brawl+ was how it alienated newer competitive players who joined the scene after Melee? It radically changed the way Brawl was played and that wasn't the idea of Brawl+. It was supposed to feel like Brawl, but faster, with more offensive options, and all around more competitive.
Taking away the infinites would be a similar thing. As much as you might like to john about it, taking them away would be a radical change from vBrawl and alienate potential players; why should IC mainers EVER touch Brawl+ when they can't even play THEIR MAIN without changing their entire playstyle and learn a new metagame?
I don't really like to resort to Sirlin but their infinites do not warrant a ban/removal. It does not over centralize the game in ANY and it is something that can be COUNTERED. Don't like the infinite? Pick a stage like Rainbow Cruise, Brinstar, or Norfair. Are all those stages banned in your tourney's stage list (for shame if they are...) pick a character that counters them. Snake, MK, G&W, ROB and Pika all come up at the top of my head.
EDIT: Looking up at a post that was made while I was taking my time to type this out, I saw somebody argue that they DESTROY some matches. To that I have the simple response of too bad. You are the only person to blame for that. Harsh as it is, it is nobody's fault but your own that I play a character that does well against them and you don't. It is called counterpicking. Even in a game where literally every character is viable and top tier there will be bad matchups. Simply because characters are made differently. Some characters are just physically incapable of effectively dealing with projectile spam. Some characters are fast fallers and will get get hit with combos to their death before they can react. Some characters are floaty and can weave in and out of combos. It is just how the game is. Learn a character to deal with problem matchups. If your lucky it won't be as bad in B+ as it was in vBrawl.
I would say that they need buffs outside the infinites, but the infinites belong in the game. They could be played without wobbling in Melee because the character was still good enough to make it without an infinite. But in Brawl they are a bad character without them. Taking it away would cripple them.
So why not buff them in other areas so they don't need the infinites? Because that is taking a character's metagame and transforming it to a point where an IC main coming from vBrawl to B+ wouldn't be able to play his character.
My vote goes towards needing tourney results before action simply because I feel that many players won't accept that it is a perfectly fine tactic in the game until they can see concrete evidence that in no way do the IC's infinites break the game or limit it in any way.
