The perk does just say 'grants shadestep' so you would think it should. Edit: I was just trying to gather an opinion on whether the description suggested it should in fact work on other subclasses. I'm guessing the misleading description is why they changed it. On a side note, some of these comparisons are hilarious, keep them up. Edit 2: some people seem to be getting offended that I was trying to gather opinions. It's just a game guys calm down. Edit 3: Had to edit the title for those very special people. Also, so many idiots comparing this to wearing the impossible machines and having landfall for other warlock subclasses. :')
