Ive been using BoS on live for a while now, to me and my friend who is also a longtime rogue its what sprint should have been from the start. I will definitely be sticking with it come 5.4 but I'd much rather they properly buffed shadowstep, its a way cooler ability that just screams "shifty, attacks from the shadows" type character and rogues SHOULD be in your face most of the time, but the CD is still too high even with the buff.
