So Kirby has enough potential to reasonable reverse 2 stock MK players of the same skill or near the same skill? I mean obviously Chu did good, but I don't think we saw enough of what Kirby is supposed to do under more varied cirsumstances, if ONLY because those situations were never induced.
Think about it this way: Say someone wants to learn Kirby. They watch that video, and apply what they learn in their matches. Now say a similar situation occurs. The Kirby player is down a stock, and has to make a comeback. They think back to what they saw in that match, how to deal with pressure, how to bait and punish, etc. Now, what happens here, if the other guy camps him back?
How does that Kirby player respond if the other guy sits back, charges Fsmash or sits there until Kirby approaches and then shields/pokes at him? What would he learn from watching that video that would REALLY aid him in if things played out differently? Sure, maybe he learned how to stifle the other person's aggression, maybe see a few follow ups/pseudo combos, heck maybe he learns how to 0-death people. But this is all assuming things turn out his way. What is he going to do when he isn't the one controlling the flow of battle?
Take Wario vs Snake on Brinstar/some other bad stage. What would be the difference between my current videos where I camp the living hell out of Snake, versus one where I approach Snake even when I have a solid lead? In the non camping one, a player might not learn/realize that Brawl sometimes is about forcing the other guy to do the work for you, or that you CAN camp without projectiles, or that you can use the timer as a means of winning a battle, or that Snake has fairly bad options for dealing with such a thing from Wario on stages like that. You would miss out on all of that in the "other" version.
Sure, maybe in the aggressive alternate video I absolutely **** the pants off of the Snake player in some elaborate 0-death trap back to back ending with a rage quit and a broken controller and tears of Shame, but players would miss out on a lot of potential info and learning that way.
