I respecced sub too, and I'm loving it. I was mainly using shadowstep to pop behind things and cheap shot them, but now I've been experimenting with using it as a damage booster. In BGs, it'd be premed, cheap shot, vanish(10% damage from stealth), shadowstep(20% damage), eviscerate.
Unfortunately right now I'm still using a sword for big hemo hits, but it'd be fun to use this in a dagger sub spec with ambush. gouge, vanish, shadowstep to behind, boomie. Sure you could go mutilate build, but then you wouldn't have shadowstep :P
Or maybe premed, cheap shot stab stab kidney shot, vanish, shadowstep, ambush, backstabbackstabbackstab
