By TNG Star Trek, the production crew made changes to the way things work in Trek and limited phasers to sublight-only.
Actually, they didn't. All we saw was that they didn't bother to show us any warp speed battles - from which it follows that we didn't see warp speed phaser battles, either, in contrast to all
the other Trek TV shows with their prominent warp speed phaser battles.
Hmm - that is a good point. A bit of luck that the production crew didn't explicitly state the limitation as published in their TNG:TM
Good examples, Timo. Were there ever any instances of any pursuing warp ship firing their weapons forward? Or were they all just about firing aft weapons at the pursuer?
