Ya lead them a little to the side they are going. It's an art if you're at the combo's most effective distance. It's a shame they took the damage down it used to be real nice, but now if you stay too far outta melee range/ shotgun range, it often looses its power to other combos, or the almighty BR. One of my tricks I used to do when I used it was my movement towards people. Imagine being observed on a plane(not the flying kind, the 4 quadrant kind) from above when you are about to fight them. You move in towards them, getting a lot of damage, and usually taking off their shields. Then at a perfect distance(took practice to find), you move back out and away, on both planes, usually in a parabolic shape. Think of how more difficult it is to lead a target that is moving away and to the side. It used to give me the cutting edge in any SMG/PR battle. Now with the BR it just seems kinda useless, no one really carries those combos too much anymore.
