Watching my battles on the battle viewer (which seems very poorly done) it doesn't always seem my ships fire all the missiles. I make big ships packed to the gills with weapons, but it looks like they will sometimes shoot 2-3 missiles then other times they will fire 8. Has anyone else noticed this?
Not sure if this is what is happening because I'm not seeing your battles, but there is a little bit of a weird behavior when you do lethal damage to another ship. All of your weapons of a certain type (i.e. missles) fire at the same time, and have to fire at the same target, but your ship will only fire enough to kill an enemy ship.
Example: You have a ship with 6 missile launchers, each of which deal 10 damage. You are in battle against two ships, each of which have 40 HP and no point defense. Your ship will launch 4 missiles at one of the ships, wait for the missiles to reload, then fire 4 at the other.
I am guessing this is an adjustment they made so there isn't a bunch of extra beams, missiles, and bullets flying around aren't actually accomplishing anything.
