Please leave your fail outside of this.
Being an extremely avid villain supporter, I won't take crap like this being fed to people who are easily bent by false logic. I'm baffled that you even think that a 3/26 ratio isn't the least bit absurd in any frame of mind. This is an imbalance that is simply dying to be corrected, as it should be, and you expect it to remain that way? What the hell...
How about instead of a misleading ratio, we try something else. PRIORITY. There is something called priority in Smash Bros - character priority to be specific. Naturally, those who are the most popular, the most well known, the most creative and iconic will deserve representation and ranking above all other possible options.
Obviously, main characters, who are often the "good guys" are chosen AHEAD of the villains due to their immediate importance over them. In SSB64, there were only 12 slots, so they chose 12 MAIN CHARACTERS from various Nintendo franchises. No room for villains. However, once Melee rolled around and the roster size was doubled, these same 12 carried over, and a few new franchises were added onto the list. But guess what, there was still some extra room for a few more characters, and so those who were next in line priority-wise (in other words - VILLAINS) were tacked onto the roster in the form of Bowser, Mewtwo, and Ganondorf. Notice this, they did not choose to add on a few more "good guys" i.e. random *** main characters and side characters from god knows which franchise that doesn't deserve representation. They chose popular, well known, creative and iconic villains who are on the level of their heroic counter-parts.
Now in Brawl, it gets even tighter this time around. With all the necessary main characters now added, let me ask you this: WHO'S NEXT? Guess what, villains. It's now time to add Nintendo's ALL STAR VILLAINS to the roster, and that means more than "just two" as you say. If anything, the number of villains in this game should be going up dramatically, and I don't know how your mentally confined logic somehow believes otherwise.
Could you imagine Brawl with a 40 character roster, and then leaving out characters like Bowser and Ganondorf? No? Well then, I guess some of those "good guys" and other unimportant side characters are going to have to take the back seat and wait their turn, because Nintendo's villains have waited theirs.
