Lol I get what you're saying PL, but a 50/50 is a guess between two options, even if the opponent is at advantage either way. Like in SF, the 50/50 for Ibuki still leaves her at advantage whether you block the kunai or you don't, but it's still a 50/50. Injustice has dumbed down 50/50s imo because it's literally just block high or block low, most setups you can't backdash or in Bane's case, jump or block lol.
But it's still 50/50s nonetheless. Crossup vs land in front is a 50/50 even though the person on the offensive is still going to be advantageous.
