For example, shoot enemy ship immune to your big-damage weapon, and the hit effect is as large as a hit that did full damage instead of a small, silent effect that occurs when hit does zero damage.
Shouldn't this be a case? A giant thermonuclear howitzer shot should explode when it hits something, regardless of whether it does any damage.

Hiteffect behaviour should probably be controlled on the weapon (so you can alter if you want no effect for no damage or regular effect), but there are issues here with raw damage and actual damage not being used in appropriate places.
I am not sure of this, but I think it used to use adjusted damage, then regressed to use unadjusted damage in 1.8a3.
Fixed in 1.8 Beta 5. Definitely a regression. Thanks!
