In general, if the boosting is really important in a situation, saturate the area with boost
Indeed, but sometimes you need to split your munitions boosters and want to just how many it takes.
Munitions boosters are seriously awesome, so ridiculously versatile and powerful even without a single point of knowledge spent.
Does the number of boosts scale with ship caps btw?
I had a thought about Attack boost...
Some units have very low attack speeds (Missile Frigates). Is there any SmartBoost or something where your attack boosters will know to boost slower firing units in range when their time is about to come up? (since it would have a greater effect)
I do this manually, but I didn't know if it was automatic or not.
No, it looks like it's static. Otherwise a single unit could boost nearly an infinite number of ships by instantly redirecting themselves to new ones every frame.
