Does armor seem like it's not worth using to anyone else?
Or is it just me?
Beam and missiles will fire first so blocking the first shot of those is more important to early survivability. Point defense especially, with the high of 36 damage from a single shot, benefit far more from defenses absorbing the full damage of an attack with no overflow even when there's only a single point of defense.
Also, with the square rooting of damage, lower damage and faster firing weapons work best against defenses, which is exactly what kinetic weapons do. It seems like when facing kinetics, the best defense would be more offense. Use the space and manufacturing time for you would have used to put up a meager defense with armor and instead put more guns in space and kill them faster.
So while I will use point defense and shields, I'm not seeing much reason to add armor. How about you?
