My issue is more so your assertion that Smash 4 isn't well balanced while seemingly trying to defend Melee as something Supremely balanced, which just seems to come from no where. You're giving Melee a lot of breaks you aren't giving 4 in your analysis.
From what we've seen so far, there's still a ton of potential for a lot of different characters to win at any major tournament. Customs throw even more viable characters into them mix. It has all the signs of a healthy balance with a strong metagame and strong future of patches with the DLC. I don't see support anywhere that 4 is unbalanced, moreso just frustration that your chosen character doesn't happened to be one of the better ones.
Excuse my rudeness, but dare I say this is an instance where you simply need to git gud.
They are, and a decent number of people seem to be moving towards Sheik as well. I'd be a little hesitant to say that there are 10 or 11 viable characters in the modern Melee meta, but no matter what number you settle on, the vast majority of the matches you see will feature at least one of those three characters, or perhaps a Marth. Just because characters have power and potential doesn't necessarily mean they're often seen at the top. At the same time, however, you have to know those other 4-7 match-ups anyway if you're a pro player. It's very unlikely you'll be fighting Ice Climbers in grand finals, but the characters are strong enough that if you don't know the match-up you're taking a big risk of not even getting out of pools.
Just another instance that make tier list discussions weird and inexact.
