Okay, seriously. No. Please quit saying stupid stuff. Indeed, it'd be nice if they just banned the people who made ******** predictions with no basis in fact.
Shield-grabbing and projectile-spamming are very basic, easy to find tactics; indeed, when I entered a new melee meta, despite being quite bad at the game I could easily beat people with my camping/projectile spamming/shield grabbing ways. The reason? People sucked, hadn't seen someone do it well before, and fundamentally didn't get what I was doing. I dominated until they figured it out. Is this a problem? I don't think so.
This is basically a wall; why should I play with you if you can't figure out how to beat a very simple, repitive strategy? The projectile spamming we've seen is nowhere near as good as it was in Melee, so I'm confused as to how you think it is a problem. Likewise, shield-grabbing was good in Melee, it was good in the original game, and I'm unsurprised that it is still good here - it is a pretty basic RPS strategy, and it works well against scrubs.
If you think the game will turn out as a projectile-spam and shieldgrab fest on the basis of one video, in which the spam is only effective because the other player clearly is inexperienced, you're a terrible player and quite possibly a scrub, or simply a troll trying to grab attention.
Seriously folks, calm down. Until you've actually played the game for a while, you're just not going to be able to say anything useful about it.
