Hello there!
I recently captured Minas Tirith with the High Elves and because it was a relatively small force i constructed Ballista Towers since i have no Cavalry to go and do something about any Siege Equipment.
Thing is the Wall Towers and/or Ballista Towers don't seem to shoot(?) reading about it on the forum some people claims that Custom Settlements can't have functional Ballista Towers, yet others said some of them like Minas Tirith DO have some sort of Automatic Defense (Even heard about some fireball coming out from time to time lol[True(?)]) but personally there is nothing shooting out of the walls.
What about Rivendell?
Thanks for any info!
