Ballista's (scorpions) and Slingers.

Shooting guys off the walls with scorpions during a siege is a site to behold. They go flying and screaming 200 metres until they hit a building then fall straight down to the ground. That was fun to watch.

Slingers being able to hit a formation behind the one they are aiming at if they miss the first row. Just don't like the size of the shots they use, it's not scaled right. Looking at them on the ground they look like grey basketballs in relation to the units standing near them. Whats up with that?
