Erron Black has trouble in the AA department in all 3 variations.
Standing 1 is very good, but only against certain characters at certain distances. EXStab, EXSlide, and EXSand are wholly unreliable. The moves will whiff or your armor will be popped. S1 is decent for crossups, but you're better off doing something else.
Also, I'm not sure what goal this thread is trying to achieve. If it's anything pompous, I'll be disappointed.
I'm saying that because it's common knowledge AAs in this game are very weak for a sizable amount of the cast.
