What the hell is with people *****ing about the balance of a game??
The only thing that is unbalanced is the skill of the person holding the controller. If you are whining about the cheapness of a character, then you are making excuses. EXCUSES. It stands a huge chance that you made no effort to improve yourself against the same tactics that ***** your face off, and instead, you decided to call the characters unbalanced. YES, some are (substantially) faster than others, but they require tons of combos and small attacks to rack up damage. The slower ones (Ganondorf, Peach) are still competetive. It just depends on the player.
I'm thinking that everyone who complains about balance doesn't know how to WD well.
Of course, some characters are just really bad and hard to win with (Pichu comes to mind). But if you're playing with them, you're a bad smasher and should switch your mains.
