obviously you're an idiot and are being so on purpose, but i can't not bite.
skateboarding is unnecessary. nothing about it NEEDS doing. i guess it depends how you assign value to "worse" or "better" skating - but switch is essentially better skating. e.g if you can kickflip down some stairs but you can also do a good* switch kickflip down the same stairs it's better.
you're also talking about pro skateboarding i'm presuming, based off the "should be done 1 trick per part" bit of the statement. none of those guys are doing no pop switch tricks where they land super sketchy and put it in a part.
i don't know man, this thread is distressing. switch skating is kind of the coolest thing there is.
