Injustice doesn't feel like it had fightsticks in mind. I've played through all the different options (turning alternate. release check on/off) but still find doing moves with Back, then Forward to be a pain when doing it within a combo. On a pad, it comes out so easily especially for using Zatanna.
On stick seems supper easy, is strict, which is a good thing. On 1 p side, D,U,BD to retreat or D,U,FD to switch sides, D,U and D,U,D are there if you mess up, which is why it is good they are so strict as otherwise would for sure be random.
I make a upside down U motion but end at D+direction I want and and it works.
air stance into teleport will just be muscle memory and practice.
