Backstep is weird, yeah. Only time it feels useful isn't even in Feast; you can use it on Carteneau Flats to teleport to ground level without taking fall damage which is cute. That said that doesn't exactly feel substantive. It suffers from Repelling Shot syndrome where I feel the animation is so laggy that if you actually want to get somewhere, the distance you made isn't that great compared to what you'd get from running. Still a net positive but ehhh.
