^^^ When I refer to point defense phasers, I'm not referring to a different kind of phaser emitter, but rather a different application of the existing phaser system, using limited, short-burst phaser shots against numerous small targets. This is exactly what the Enterprise-D used against the Lysians in the episode "Conundrum". There is precedence for this. There is also precedence for cluster photon torpedoes that could be used as an effective anti-spacecraft weapon during an approaching swarm.
I don't care how many forward-facing turbo laser batteries (emphasis on lasers
, BtW) a SD has. Once their TIE pickets are wiped out, beaming a single magnetic bottle containing a spoonful of antimatter in the SD's main engine core will make short work of it.
