And in terms of the lack of phaser coverage aft, if the existing phasers leave blind spot I see no reason they can't have tiny point phaser emitters a la Lakota or Defiant. If the Ambassador was really a pathfinder kind of ship, I see no reason why they can't have a mix of weapons technologies in the design, even as a redundancy in case the fancy new phaser strips don't work out well.
Agreed, and a good point - both the Lakota
and the Defiant
seemed to have phasers coming out of, well, nowhere. Tiny details that don't seem to correspond to phasers we've seen before.
