You can escape 1 combo almost guaranteed with burst (unless u get read hard).
Also DI is not a slight change in speed/direction, good DI drastically changes combo routes to the point that u can force them to drop the combo early and frametrap/setup instead bc they can't follow it up.
If you just leave the match the moment u get hit u'll never learn how to escape combos (which is a mindgame by itself).
