This is possibly the most common Sakurai misquote. Sakurai meant that they were unbalanced in the sense that
more experienced players who had more of them would have an unfair advantage. This myth needs constant debunking, and is incredibly obnoxious.
And if they weren't balanced for,
why did the game's only balance patch include changes to custom moves? Dragon Rush got dropped from 15% damage to 11% damage, for example.
Miis may be "custom characters" but have a clearly-defined moveset and are playable in most game modes. Villager's planking has not been widely explored; to the point it has been, it shows itself as obnoxious to counter, not unbeatable. Customs in FFAs? How does that have any relevance? Characters with bad recoveries getting good ones... Um... For example? Almost every single example, there's a clear tradeoff (hell, most Little Mac players prefer the
default moves, rather than the upB that grants him a better recovery, and numerous characters give up a good recovery for a worse one, such as DK and Wii Fit Trainer). Everything you're saying makes no sense.
And yet overall balance and playability is still somehow better with Customs, Miis, and numerous stages.
How did that happen? Either Sakurai is so awful at balancing his game that we shouldn't pay any attention to what he has to say, or your stipulation is simply
wrong.
That's some pretty weak excuses. They do stock in 1v1, and while team attack off does keep trolls of one nature out, it lets trolls of
another nature in (and anyone determined to screw you over can take all but one of your team's stocks by just SDing twice, stealing a stock, and SDing again). Additionally, I don't know if you've spent a decent amount of time playing teams with TA off, but it's
stupid as all hell. Even just something as simple as two projectile spammers backing each other up is incredibly difficult to stop due to how they cover each other. It's badly balanced to the point that it completely destroys the idea that the game was balanced around For Glory.
The fact that they addressed that alone is actually another nail in the coffin. Not only did they nerf a 2v2 strategy (meaning that they care about teams balance) but they nerfed one that
does not work with team attack off!
Have you
seen decent Little Mac players lately? The idea that Little Mac "only works on FD" is simply wrong. He's not a
good character by any stretch of the imagination, mind you, but he isn't a good character even
if FD is the only legal stage. He's got a lot of stupidly hard matchups (Kirby, Jigglypuff, Metaknight, Pikachu, Shiek, Megaman, should I keep going?), all of which get
better if FD is the only legal stage, but they all simply go from "you need a secondary" to "you're gonna wish you had a secondary". Some of them, like Captain Falcon, actually get
worse on FD.
But beyond that, the idea that he's useless anywhere else is just hilariously wrong. Mac is capable of competing on most of the tournament viable stages. Basically, anything other than Kongo Jungle and Duck Hunt, he can do okay. Check out some of Espy's videos if you don't believe me. But even given that...
...This statement is hilarious. Low tier characters
always have significant problems. Remember Melee Kirby? Brawl Ganondorf? They worked
0% of the time. Because they were terrible. Mac has awful aerials, a terrible grab, terrible throws, and no recovery. The character's design is fundamentally flawed, and no amount of coddling the stagelist to get around this solves this.
