1. Weapons platforms are far from useless, during the event awhile back between the LWB/Hessians and RM out side of the prison in Hamburg the weapons platforms did as much if not mode damage as our ships.
2. I heard from a fairly reliable source that NY is full. That is its got as many basses and objects crammed into the things as the game engine can manage and one more thing would turn the system into a black hole so to speak.
EDIT: You could just replace station turrets with something that was meant to drop more than a class 2 shield.
