Airblocking would turn it into a spam war, waiting for an opening. Projectiles would also become key, in order to cover more of the stage while waiting for the enemy to expose himself.
I have no idea how air blocking would work, but I wonder if projectiles could break it=? I really wonder if it is in the game or not, but the spam war is dead on. Good solid point, and this is another odd consequence of online play.
Then again, this could happen in so many diffrent areas and aspectso f the game, hacking air shielding would be easy to report, and quickly abolished by hackers most likely (if Nintendo has some reporting on misuse of game thing).
There are ton of online hackers, and we could face some (ex: people who have "fixed" Xbox's to make them get better stuff, new features, or more health in games like Halo 2). Despite this, all who do that to cheat online=lower than noobs, who can't fight a fair fight, or even win or lose a fair fight.
Also, patches could help prevent hackers, and multiple fields could be targeted for hacks. In that case, Nintendo might add auto update patches. I doubt Nintendo will use downloadable content, but if the hacking gets bad, well they'll have to use patches.
Projectiles as a weakness for air blocking, I like that. Another possible feature is you can only air block attacks from the front. Then again, air blocking lasting less than a second would work. It definitely could add some more tatics to the series, especially air combat.
Considering how I want better air combat, this would do nicely, but only if done correctly. Otherwise I say to heck with it, no exceptions, unless of course, it works or fits nicely. Overall, depends how it would work. I don't support it, but I don't say discard the idea. I want to see someone come up with a really good scheme for this, to make it work like a dream.
I got a good idea for it, or at least a example. Link uses his shield to block attacks, and it only works for a while, or MK uses his cape. Junk like that could make it work nicely. Of course as I have previously said, a certain balance is heavily needed, otherwise it will be a sheer utter failure. Plus if it would be in SSBB, it should be a option (much like items).
