"fuck it throw it out" is precisely the kind of thing you don't want in a fighting game
When a game is balanced accordingly, I think you're wrong. Obviously it won't be that quite extreme once people learn the game better and are more keen, but it's hard to explain because I don't think Smash falls into the same vein as standard fighting games.
I'm not saying that I think it's going to be "CHEAP MOVES WIN!", I'm saying that I think the entire game seems to be more balanced around using more of what each character has to offer. Instead of just sticking with the safe effective moves, you have more flexibility to catch people off guard with more unsafe, powerful moves.
