@Tesh: Developer intent means nothing.
@T-Block: I do agree that a lot of it has to do with being an ingrained standard, but Smash has always been a game of momentum. One stock doesn't seem like enough to me, I tend to do my best when third stock hits and it's game time. :X
I do agree that it's a bit of a double standard, but here's how I see it.
With 3 stocks, no food, ledge play and stage play are equally encouraged. Ledge play might be TACTICALLY SUPERIOR, but we're not ENCOURAGING it any more than the other.
When you change things to 1 stock, with food, you're DELIBERATELY discouraging ledge play, and saying, "Stage play is 'more fair', get off the ledge, or we're going to remove some of the lead you've earned, be it ON stage or off-stage."
What's more, is you also skew balance towards characters with good edge-guarding games. If you can hold your opponent on the ledge long enough to build up some food, you can take off a good 16% or so while STILL racking up damage.
Also, this all stems from the notion of being unbeatable on the ledge, so food is a counter-measure for that because it lands on stage.
Why wouldn't you skip the modifications and just remove the main source of the problem? MK.
This kind of idea doesn't seem sufficiently convincing to me, considering how much it would change the metagame, all in the name of dealing with a more specific problem.
Play every stock like its your last. In my scenario, your first stock is your last. As far as momentum, thats just irrelevant and subjective. You get a short 5 second break if you choose after each KO. If momentum was so important, then separating a set into nine 1 stock matches if "horrible", three 3 stock matches is "bad" and one 9 stock match would be "best".
Developer intent matters about as much as our "standard" because its how the game was before we change anything. I personally don't care too much about it, but I know some do.
Obviously changing any relevant setting is going to "nerf" or "buff" things. Its not like anyone ever suggests we adjust the colors or aspect ratio. Any relevant change is going to have its effect on the metagame. Ever consider that maybe putting 3 stocks instead of 1 was an arbitrary buff to characters with good ledge camping?
The ledge is obviously a very fortified position that makes bad characters more manageable (jigglypuff), mediocre characters good (pit) and the best character too broken (MK). Putting a "reward" on stage definitely helps balance out the camping zones on a stage. The middle of the stage is the hardest to defend as you are vulnerable from all sides, but it gives you the best chance of controlling the "reward". BTW the tactically superior option IS what is encouraged. Food isn't going to rapidly eat away at a massive lead, but it does put a dent in any kind of excessive stalling.
Sure I can see some obvious metagame changes for characters:
-Snake's stage control would be more impressive
-Lucario would lose some helpful aura effects
-Wario would probably only get 1 or 2 farts per game (though he only needs 1 now)
-Pokemon Trainer would be alot better, as you can completely avoid using the worst pokemon for the job
-Pit would probably be the best ledge camper because he can still punish you from across the stage.
I wouldn't say counterpicking becomes drastically more powerful. Considering you only get your best stage for 1/9 of the set as opposed to 1/3 of the set. The fact that you had to endure mk/rc, sonic/YI or diddy/fd becomes far less powerful overall.
I'd personally love to see a solution to out problems that doesn't change ANYTHING about the metagame. I challenge anyone to make a ruleset with less problems than the current one. BUT, the tier list should remain the same, gameplay should be exactly as it is now. No character should become better or worse because of the ruleset.
I'm not seeing why any of this is "bad" as opposed to "different".
