I like the games very much but I feel there is no necessity of Missiles in the games. It takes long time to reload, very bad accuracy and spends all scraps in stores for missiles ammo.
In most of my games, missile weapons benefit the enemy more than the player. They always fire one off before you can disable their weapons system and the missile always targets the system you need the most, breaches it and sets it on fire. Especially the 1 damage Leto missiles. They can fire one every 8 seconds.
Missile weapons do have their uses though - as free scrap!
Also, missiles don't have bad accuracy. The enemy ship just has high evasion. All weapons except for beams have the same accuracy.
There's also the Artemis Missile for maximum BS potential - 2 damage, 10 second charge. Really hate it when the enemy has that.
