There was talk about this when in beta and I'm not sure why it isn't implemented (unless I just missed it).
Why doesn't the shadowdancer have an ability that is similar to the monks abundant step and the FvS's wings? The shadowdancer jumping ability from PnP is much more similiar to the current abundant step than any of the classes' ability that currently is used as abundant step or the likes. That was the biggest thing I was looking forward to in this destiny too. :/
