This is definitely not true. MK11 AAs are better than both MKX and Injustice. You can actually jab AA more consistently than either game, and d2’s actually work, unlike before.
I was referring to MK9, MKX and MK11 - sorry my bad, for not making that clear.
I can't really get into d2 discussion, as I was never really a d2 fan boy.
Now I had personally almost 8/10 success in other games with poke AA system. Unless it was character specific, I can't agree with you. I believe the difference in opinion may come from personal experience, which in your case, you clearly, were either mashing, or had but reaction - which is fine, by the way. I was in your shoes, years ago.
There are plenty of things I don't know, and rarely I participate in discussions, but when it comes to AA'ing I can safe say, I lost a huge part of my life, mastering optimal options, and obtaining high success ratio.
But again, this is very subjective opinion, and will vary from user to user.
