Thank you for the kind words! My intention for the ballista is that it would be a single-target tower. This means that from each shot it could only do 1 damage to each enemy. The slingshot has the same effect at a much lower fire rate but, it leaves behind a cloud of smoke that deals 1 damage to anything that is in it or walks in it. This means it's good at clearing out lots of enemies that are grouped together. Hope that makes sense. I didn't have time to make more visual or audio cues to make clear what what was happening
