I think we should look at the frame data first. There is a precadent for ridiculous crap in NRS games, but they've always been that way.
But I've said that people should try something before freaking out since...forever. Since like...MK9. No one cares. No one will know anything until they actually play the game. All this agenda-pushing and scare-mongering is a waste of time.
These games have always had fucked up stuff in them, always. Injustice wasn't some Honest Man's Game and those that tell you it was are liars. Sinestro Pushblock glitch, Batgirl's "infinite" that was hot fixed out, MMH's teleport, Scorpion on release, Flash, Bane(with Venom, he could buff the damage the interactables he threw did), etc. There were a lot of ambiguous cross up set ups, looping vortexes, etc.
Ultimately, the people that like the game will grind, compete, and succeed. The people that don't...won't.
That's all I have to say on the matter.
