Don't mix boom and zoom, turn fight etc. with Lag Roll maneuver. Lag roll can be used to cut corners if you have E advantage and keep you E adnvantage. If you overshoot executing lag roll and loose to much E then you are misunderstanding it.
Use it when you have more E and enemy is turning and you want to keep pressure, or when attacking unaware enemy who is changing direction.
And ofcourse using Hartaman's tactics is always the safest pet
Topic is when to use Lag roll manuver
