Unfortunately, reality does not jive with your statements here. You don't need to be especially good to end someone with a Smash Ball that just happened to spawn on your end of the stage.
Considering that you have to hit the Smash Ball something like 5-7 times to activate it and every hit sends it to another part of the screen, yes you do.
Maybe, like, a small child or something will fall off the stage like a god damned idiot, but a pro could easily get destroyed by someone merely competent in a tournament set because of dumb luck.
In other words, if you're going up against a Pro with an item, his skill surpassed yours in getting to the item and using it first. So he beats you. And this is a problem?
This is all hypothetical, by the way, because there's roughly zero tournaments for Brawl with items because it is a degenerate dicerolling game.
Ok, quick poll: does anyone besides
this guy give a damn about how this party game fares in a tournament scene? Does anyone think the vast majority of Smash Bros. players do? I certainly don't.
This reminds me of what happened with BlazBlue: Calamity Trigger and it sequel Continuum Shift. In Calamity Trigger, Aksys smartly made the most complex special moves in the game easily performable through Right Stick shortcuts. Anyone could jump into BlazBlue and easily enjoy the things about the game that made it fun. But then the tourney players started bitching that anyone
could do these button combos that only they
could do before, and Aksys removed
that feature from Continuum Shift.
The end result is that I can't enjoy the game now because I just lack the ability to type in button/stick sequences like that. And I didn't even play online! But my enjoyment of the game was destroyed by people who didn't like the "commoners" being able to compete with them on an issue that never should have been gated off like that to begin with.
That mentality of appealing to the hardcore tourney players is how fighting games have become a gated community where newcomers are not wanted. It's why I don't play them.
