Interestingly, the idea of running away from enemy torpedoes and attempting to shoot them down while trying to sneak up on the target under cloak was addressed in "Balance of Terror" because the shields were ineffective
against the enemy's weapons fire.
But with effective shields, the tactics switch instead to hammer away until you win by downing the enemy's shields. And when that happens (in TOS anyway), they'll have expended so much of their power that escape is unlikely unless they were smart enough to make a run for it earlier with their reserve power.
I do agree that TNG and later series devolved it to a point-blank affair between simple phasers and torpedoes.
