If missiles get these improvements, then I would also ask for each missile to take up 2 ammo slots instead of one, leaving a total of 35 missiles. This would put those in vanilla ships at a serious disadvantage, adding to the ones present already.
You already see very few if any people in a werewolf. This can only make instances such as this worse.
Missiles are already very good, and it takes only a few mistakes and you lose your guns if not your ship. I do not like the idea of missiles being used as an "equaliser" for less skilled players to use against more skilled players, which is essentially what such an upgrade would do. Six missile launchers and any opposing player could kiss his backside goodbye.
