There have never been too many Puff players. Seems like I can't ever remember there being more than one or two prominent players of her at a time.My personal suspicion is that most tournament players find Fox/Falco/Falcon to be the most personally satisfying, as the link between technical skill and achievement is no more clear than with those characters. Most players who challenge themselves with competition enjoy seeing that curve in more tangible form. While she is certainly an effective character as a whole, Jigglypuff has a limited number of effective tactics that doesn't especially branch much with skill growth, which causes some players (Mango, for one obvious example) to get bored. I think there's truth to what Massive said as well - the technical game is just not as important as the mental game and that is hard to practice on your own.It's an interesting question, though. I'd ask the same of Ice Climbers - it seems like they'd be good candidates for my theory above, but that hasn't borne itself out, possibly because figuring out their tricks on your own is nigh-impossible and by the time players come here they may already have characters they prefer. There's also the "showing-off" theory - that most spectators don't have a clue what the IC player is actually doing with the controller, making it harder to impress people with your skills (which, conversely, is yet another argument as to why Jigglypuff players are rarer). Tournament players definitely like to impress people with their skills.
