On probably an unnecessary note, I noticed that if you're at a slight distance and cut the ground string in half, the combo becomes worlds easier on most characters due to lack of gravity increase. So, even if the full combo doesn't work on everyone you should be able to go into j.[C] combos by sacrificing a little bit of damage. Either way, if you get a random counter hit during stagger or something you're usually too far away for the full string anyway.
Oh, I also found a way to get an extra j.[C] or
two in off of mix-up against some characters. It probably would work better after scaring them to respect 22C, but 22C allows you to get the extra hits anyway. Might be able to get this off after random CH 6C's, too?
Ended up going 500-700 more damage depending on how the flame hits.
22A~9j.[C] > 7~j.[C] > 5A (whiff) 6AA > j.[C] > land > 8~(while falling)j.B > j.C > land > j.A j.B > jc j.B j.C > air throw
Sadly starting to look like there's not much incentive to block low aside from not wanting to get thrown into the same situation again. Working out the details later when I have time.
