I'm actually not a fan of 1A : A : A this time around. It has niche use as a close range step killer, but honestly, it's just not great and IS reactable.
Ah the famous debate from SC4 ha ha ha. Is 1AAA reactable? Ha ha ha.
French top players can't react to it. They couldn't react to it in SC4, and now it's even one frame faster. I don't want to sound like a jerk but I don't know who are the Machines you're playing with but they have sick reaction time to be able to see i22 move with deceptive animation. Reaction time better than Keev. Better than Malek. Better than Saitoh. Better than "normal" people anyway.
You may find it is reactable but you just need to find setups where opponent can't guess it's coming. You get this move blocked? Your opponent doesn't have good reaction time, they have good mind game and you failed your setup.
My top 10 :
1AAA : one of the best low in the game
2363B : tracks, can be delayed, good launcer
Throws : damage
214~3BB (+BE) : Auto backdash, combo CH, safe, and you can BE even if they JG. Correct answer for them is to step. I've been spamming this move but I dunno how good it will be in the future because of JG and step.
214~2K : nice range, nice low.
214A : her best antistep tool. +8 CH. Deceptive range.
214B : antibackdash, very good range
214~3aB : punition, damage, TC
44B+K (BE) : punition, damage, starter
2A : allow mixs up
Honorable mention to :
