How to perform Lag Displacement Roll Attack?

[Masi67]

If you coming on his six with more E and he turns you can setup attack with lag roll. Key thing is that you need to do it on right time not too late.MAXGUNZ is right that if you see that you will overshoot then you need to do something else. No single attack will make the difference if target is aware of you. Lag Roll is usable on some situations but not for all.
