The Picard Maneuver never made sense to me. First of all, how is it no one before had ever used the "light lag" effect to make a tactical advantage?
I like how, in the many years since the Picard Maneuver was first used, nobody had been able to develop a defense against it, but Data came up with one pretty much off the top of his head and it was almost as simple as the Maneuver itself.
Itís a lack of creativity by the writers.
Well, Data did make the point of saying that the Galaxy class had enough power to pull off the defensive maneuver he suggested.
So that tells me no ship before the Galaxy line had enough power to pull it off, even if they had thought of it.
