I said it before and I'll say it again since these arguments are going nowhere.
People are not against splatdashing because they think speed is unimportant or unneeded. These are not the things you should be trying to prove in your counter arguments.
The main reason is because there is no proof that it is the fastest way to get around. It was tested by me and others, even the guy who made the video for the fastest way to splatdash, and we all came to the conclusion that ink trails are just as fast if not faster than splatdashing. And if they are just as fast, there is no reason to splatdash since ink trails have a lot more pros in other areas to make them the better choice.
Whether or not getting to mid fast is a "HUUUUUGE ADVANTAGE" can be left for another thread about the meta in general once the game actually comes out, that's not the topic here. If you want to prove that splatdashing is viable, I want to see a properly timed proof with optimised ink trails as well as optimised splatdash. After seeing what FunkyLobster thought an optimised ink trail looked like I get the feeling that possibly the rest of you are terrible misinformed on ink trails movement potential as well, which is why some of you think so highly of splatdash and ignorantly claim that there is no way ink trails can be faster; because you were doing it wrong to begin with.
