-Jumping never worked like it did in other fighters, as in hopping over a grounded opponent. It basically was a tech jump to avoid lows. In its place, All characters in the game were given aerial attacks, with others having aerial maneuvers that allow jumping over downed opponents to get back turned advantage. In Doa it is a specialized technique not an universal mechanic.
-I think you are misconstruing these players views as not wanting the original jump feature returned, as them not wanting a good game. This is not the case at all. I was upset with its removal at first, but most of what you are asking for is clunky and convoluted. It is much more streamlined and deliberate.
