3. BUT till the ballistas get rid of a raid I would have killed the enemies at least 2 times by hand without wasting ballista bolts ...🤪
4. But after beating midlands there was never ever a single situation when the ballistas or the traps were needed.

Needed or not; they're useless.
If they weren't useless it could be coupled with an automated wood farm to automate killing minor, annoying enemies that everyone complains about.
For some of us, the thrill of killing countless dwarflings has somewhat lost its thrill.
