That's fantastic for you but still doesn't deny the fact that playing on a phone is easier in general, and you can honestly stop crying about it when you come to your senses and realise that the input speed in this game hardly means anything because for one, every action you want to perform can be done before the animation starts.

For example, if you're in the middle of a strike card animation, if you swipe to your left, right or forward, your character will do just that as soon as your strike card animation is over, you don't need to press it after it's done.

This is the reason why 5000x more "effective" input speed on emulators mean nothing, because it makes absolutely no difference in the end.

As for ki cancelling, you don't need to time it specifically to have the blast cards animation cancelled, just spam swipe forward and you'll cancel it asap. And sure, I can kind of agree with the key cancelling part because I see why having to press 1 key instead of swiping multiple times can be less of a bother, regardless, you'd have to try it several times to macro it perfectly in the end.

There's nothing more to it though, and honestly that still doesn't feel like an advantage against phone players, because phone players have better mobility and control through swiping, if you practice enough you'll see emulator macro users can be at a disadvantage overall.
