I strongly disagree that scoped weapons are "just better" Scoped weapons get slowed down when charging and have a limited view that non-scopes don't have to deal with, the trade off with range really isn't worth it. Scoping a weapon essentially makes it far more defensive than it needs to be, and splatoon is certainly a game that requires everyone to move effectively. Scoped weapons are certainly for a type of play-style, but they just don't "outright" outclass their non-scoped versions./.
super jumping is generally a bad idea, the time you are super jumping is time that you could be covering ground or making a new path or approach. Generally in the video he covers that it's far more optional than people give credit for. If you only already have your bases/path covered and the mid point is controlled, ya super jumping can work, but generally you want to always ink something and gain more for your special.
