I have practiced for an hr, couldn't get the dash cancels 2 in a row. Easy for you, hard for others. If you can do it then great but a lot won't be able to. The others are just trying to provide combos that literally anyone can do as there are minimal inputs and lenient timingYou're right, I was about to edit my post to include j2, same for b1.
It isn't even optimal - just requires 30 seconds of practice, its really that easy. But what do I know, apparently my execution is F tier .
