Right, I'm saying in the scope of assumption that the system is done well and balanced this time around. I didn't assume it would be the exact same as Brawl. Also, I only meant "spammy" Fox as one that uses it too often as a go-to kill move. It would be nice to not have to panic every single time you are above Fox because you are probably going to die. This was just an example anyway, I could have said Bair spammy Jiggles and meant the same thing. Sorry for the confusion.
As @

said, the system already seems more balanced, in that more characters are able to use more of their moveset and still get the necessary DI out of it. If done correctly, the system would open up players to using more of their character's moveset, thus seeing slightly different matches. Also, as another thread is discussing, Smash 4 and Brawl both leaned a little less toward technical skill and more toward actively being strategic about your moves. Stale moves, done correctly, only enhances that idea. Smash 4, as others have said, seems to be finding a nice middle ground between these two ideas, which would make for an accessible, but still competitive/strategic fighter. The prospect is very exciting.
