In a competitive atmosphere you have to assume that the players are playing at the top of their game and utilizing everything to its fullest ability. While this may be a bit of an exaggeration, when you realize that top players probably aren't going to allow you to use your unsafe moves or get combo'd it makes sense to assume that competitive play will be limited. Especially when the game also makes it stupid easy to avoid such things.
To add to this:
When you reach the top of one mountain, it becomes easier to see the tips of other mountains as your head is already above the clouds.
Thus, if your brain is trained to think in a competitive gaming sense, you're able to see the depth, or rather in this example:
mountain height, more accurately than if you had no competitive training at all.
It's not too preemptive to critically judge the game's depth. What we're dealing with right now is "Human Tiers". Ichida being decidedly low tier, is wholly ignoring what very prolific smashers are saying. And, in the face of cold hard facts, is simply arguing with laughter. We're not laughing with you son, we're laughing at you. When all of this is said and done, after Ken, Isai, Hugs, Wife, Husband, Azen, etc leave, perhaps you'll be the greatest Brawl player! But really, is it worth it to be king of such a small mountain?
The verdict is still obviously out, as there's still so much to learn. But given our current knowledge set, and our reasonable ability to gage what may be discovered, it isn't too far off to say that we're searching for things that just won't be there.
