I think the Metaknight mains would be just as rusty from not playing as their character... <_<
True, but the point is that it will stall, therefore it will accomplish nothing for that purpose.
They'll learn the MU again. Fast.
Since any major tournament that was reintroducing MK would likely advertise that fact ahead of time as well, anyone serious would spend some time practicing and regain their anti-MK techniques.
Did you ever spend time fighting Dr. Mario, before stopping and letting your techniques slip? Or are you bad against him because you never had a way (Or reason, as appropriate) to get good against him in the first place?
Your point sounded more to me like new techniques wouldn't be found against MK (And I think practicing/MM's would test any new character techniques against him) though, not so much people forgetting how to fight. However I don't think that's really a major problem either.
You're missing the point, I'm not saying that MK players will do better, I said
NO SUBSTANTIAL CHANGE.
There's a major major difference.
Metagame advances don't come from new techniques appearing out of the blue, they come from people learning how to apply the techniques in matches. Often these are existing techs, sometimes they're brand new, but in general, people will become used to a metagame without MK, and what will that accomplish? More then likely, any new techniques will take long enough to apply to MK that it won't be substantial.
Unless something truly gamechanging comes out (which is unlikely), then a temp ban is meaningless in terms of helping other metagames advance.
It's for data collection if it happens, to make a decision on whether or not MK will be banned permanently.
From what I've seen most Brawl matches don't come within 2 minutes of the time limit, and the ones that do usually involve lots of stalling. Remove the time limit for matches, actually enforce the stalling rule, and keep the ledge grab rule at 40-50 ledge grabs.
The first removes the real reason to plank (forcing time out and winning by default), the second is something that needs to be taken seriously regardless, and the third puts a serious penalty on planking on top of the stalling rule (only suggesting it because of stories I've heard about stalling punishments amounting to "stop stalling please").
Now somebody point out how this won't work so I can get the idea out of my head altogether.
I'm playing I'm playing Zelda vs. Pikachu, what's my reason to approach... ever? What's pikachu's reason, neither character can force the other, and they make themselves vulnerable, so why?
That's why timers are there, to force a conclusion.
