imagine the game "mechwarrior" - which consists a LOT about anticipation and customizing your mech. - take away customizing the mech - and the game itself becomes boring. - take away the ability to customize your ship in freelancer and you ll loose a major aspect of the fun.
That is exactly how i think.
Freelancer without customizing weapons isnt "Freelancer" Its BORING. Discovery has barely any raw customization (engines, powerplant, ect) that some other mods have, dont take this away too.
