I'm glad I'm not the only one who noticed this
Fact is that the people who used to play her are too busy IRL now to keep up/keep attending tourneys and there's no influx of people to replace those who go
(I've not heard publicly of any names, but I think there are certainly new players out there making a name)
This is probably to do with Peach as a character - her playstyle is so radically different to every other character and her learning curve is horribly steep. All of this combines to create a very off putting character to pick up imo, especially when you could easily just choose someone else and do as well, if not better
(Partial truth. Peach is a difficult character to pick-up without much easy rewards. Diddy is hard to pick-up, but learning his stuff provides much better situations than peach's.)
And at this stage in the metagame (because let's face it, Peach's and indeed Brawl's metagame looks like it's peaking or potentially peaked) why bother picking up a decent character when you could pick a top tier and stand a better chance of winning?
(People who actually like the character's mechanics)
An MK ban in tourneys could go either way - on the one hand, it would bring in more Snakes, Falco's and Marths but on the other, it means that people can focus more on those match ups since everyone runs around focusing on and worrying about the MK match up. Plus, more Wario's might run about the place which would be a plus for her
(I sort of agree that MK ban is a plus for many characters. Even if there are more of other characters, it's possible to learn it.)
As for these boards...well, I hate to say it but the place is nothing more than a chat room now. Certainly some 'interesting' conversations about the place but a chat room nonetheless
(That's everywhere in character boards. There honestly is never much to improve with characters as you said.)
The people who post the most don't attend tourneys and the people who do attend tourneys don't post or post very little. It's always been a massive problem with this board - it should really be the opposite way round. Everything is either incomplete or out of date guidewise because people have lost all motivation to discuss these sorts of things and it doesn't help that there's a next to no Peach players to generate healthy discussion. It's just the same people saying the same things over and over again so there just isn't any point
(Point above. What would you discuss? Old guides still work relatively well in a non-changing meta game. If you want to do much of anything, you need to get into some super serious theory discussion and go into super detailed specifics. For example, what way to DI common moves to place yourself in a better position. MK dthrows you, do you DI down and tech, or DI slightly away and up, or is it something to mix-up.)
Everything is horribly stagnant and it looks like it's going to stay that way unfortunately. I personally have really enjoyed visiting these boards and I still do enjoy visiting them but the way I see it, Peach and the Peach Boards are dead unless a new influx of super good Peach players suddenly burst upon the scene
