In my opinion the autodesigner for ships is more or less worthless, primarily due to its ignorance of any components besides weapons and defenses - no engines, no sensors, no hull modules, nothing. I usually just turn it off to avoid clogging up my shipyard screen with designs I'll never, ever use. I've come to suspect it's similiar to how AI opponents design their ships, which make their horribly slow speed a little more comprehensible.
So I'm curious - does anyone on here actually bother to use it?
