idk if off topic, but, I always find it weird that any missile weapons don't just retarget the enemy and instead self destruct, if anywhere, this should be at least done on cybran cruisers to make their aa less trash in comparison to others, so far nanodart was changed from what it used to be (slow moving missile that speeds up over time) to be more in line with what other cruisers have (immediately fast moving missile) simply because of how bad it originally was even disregarding overkill, and is now about as good as other cruisers at it, but it lost what it originally was
so if it could change its target mid-flight, being slow moving again but able to retarget might in fact make it more unique of weapon, letting cruisers create a "cloud" of damage above them that anything flying through would get wrecked by, like a flying swarm of mines, instead of just another boring missile weapon that instantly gets full speed and charges directly at initial target like all the others, but of course idk how sim speed would like having so many missiles in the air at same time, looking for targets
for uef and aeon I instead suggest, like you said, simply making them target properly like tmd does, to not overkill, but idk if that can even work for units with different hps instead of homogeneous ones (tactical missiles) that are all same hp
