Okay so I've been messing around with the Shinobi for a bit now trying to get him repped up as far as the other 13 characters and I came across the marvelously hysterical discovery that you can use the Shinobi's running slide tackle to intentionally throw yourself off cliffs that you can perform jump attacks from (not ledges that result in instadeath, but edges where you can hover over to drop down on an enemy below). This is a feature that should be prevalent for all characters who have running unblockable shove/rush type abilities, if you use them too close to an edge, you should barrel over and fall yourself. I'm not sure if you guys have any plans to remove the invisible wall from all ledges, but I feel that in the meantime any character with an unblockable type sprinting attack that throws their body weight around should be able to throw themselves over "jumpable" ledges. For realism and comical purposes, of course.
