in the corner to do the hit on both sides j3 wouldn't work but if you get a hit then yeah that would be the best, j2 if done right leads to a 50/50 so i would do j2.
Ji3 is positive on block (+5) and gives a bigger hitbox to The Flash (the timing is more tricky however). Following so by 3, 2, is good because you do not need to know one side in particular to make the inputs properly. Doesn't matter if it's on block or on hit (you cannot guess before doing the inputs anyway). So Ji3 =>
on hit : 3, 2, reset spot.
on block : 3, 2 RMc back dash.
This is the best option midscreen imo. Don't know why it wouldn't work in corner.
