This smash is really well balance like I said earlier. And it's said to be such because its exactly the opposite of what you just said. none of the characters feel like they totally outclass any of the others. Every character feels like they have enough tools to be able to win against any other character in the game.
That's why I see the same characters online and have rarely ever seen some of the other characters. I see the same 10 characters all day and it's no surprise they're ranked the highest on every tier list. There is a long list of characters I've never seen online so far. It's actually a little sad because some variety would spice things up.
