Well a rule set is just an extension of the game.
A ruleset is not the extension of the game. You have no game sans ruleset. In a very real sense, the ruleset
is the game.
You can't make a rule set that has no bias, since you are immediately going against how the creators of the game intended it to be played (2 minutes, all items on, all stages, FFA, best of 1).
Some choices are arbitrary and must be made. Banning a stage does not fall under this. You also keep referring to bias, which is peculiar since it's not something I've mentioned. I have no problem with bias in a ruleset, it just needs to be justified. I don't expect objectivity per se, but that doesn't mean all decisions are equally justifiable.
As soon as you cross that threshold into changing the game as you see fit -- which affects nearly everyone that plays the game -- a burden of responsibility falls on your shoulders to make the rules "fair". Because "fair" can be subjective, we made the rules with a large group instead of a single individual, which helps to remove bias.
We're not "changing the game as we see fit" from the beginning. At the most, we are making the arbitrary decisions where they need to be made: what game should we play? Should we play stock or time? How many stock should we use?
There is a large jump in logic. Why does it follow that you have to make the ruleset "fair?" You haven't even
defined fairness. All rulesets are inherently fair provided all aspects of the game are available to all players. So what do you mean by "fair" in this case?
All rules are subjective.
If you mean to say that all rules are justified subjectively, then I might agree. But this mean it's ok to make arbitrary decisions.
To stonewall a rule for lack objectivity is backwards. Rules are like assumptions, they are either good or they are bad. In this case, reducing the stage list is good because it adds consistency to the results and it allows for more viable characters. Claims like, "falco players just want to ban brinstar because they are scrubby" are ignorant at best.
Consider the following argument:
"Banning Sheik is good because it allows for more viable characters."
It's the same justification, but the logic is disagreed with. Because, when it comes down to it, "good" and "bad" are useless words that people will and will not agree with (we notice, for example, that "no items, Falco only, Final Destination" makes for a very balanced game with very little variance; most people would not want such a ruleset).
The reality, and you're welcome to call me ignorant, is that all of these rules are made out of scrubinness. Maybe they're made with some misguided good intentions, but they are scrubby. Because the justification is scrubby.
While I have an issue with too much subjectivity in creating rulesets (e.g., I think the game is infinitely better without Falco, but I would not ban Falco because I know this is just opinion), I don't have an inherent issue with subjectivity. There will always be some subjectivity in creating a ruleset (for example, the decision to play this game over any other, the decision to strike for the first stage instead of choosing it randomly, etc.). My main issue is with the fact that there appears, in most cases, to be no set of criteria to base these rules on. People just decide what they do and don't like and use that as justification for bans. In the cases where people do seem to have criteria (e.g. you and Cactuar), I highly disagree with these criteria, mostly because they are scrubby.
tl;dr we shouldn't be banning anything for balance, unless the balance issues are extreme (i.e., broken).
Brinstar is one of my characters' best stages and I didn't want it legal for reasons stated for over 50 pages. Deal with it.
Deal with what, exactly?
The MBR also has stated several times that the stage list is not an opportunity to artificially balance the roster, so I don't see why you (or anyone else; SVEET) keep bringing that up. The ideology we use for our stagelist is for the stages to have the least amount of interference with the outcome of a tournament set.
Cactuar has actually said things are banned in the interest of balance (not necessarily only balance). My guess is that things are done democratically, so every individual in the MBR thinks that things are banned for a different reason.
