Currently, almost everyone I think will agree with me when I say ballistas are overpowered. The current meta is something like take mid>set up tower>rain unstoppable explosive rain on your opponent while knights jump down spamming the 5 emoji. As is, it's basically impossible to stop ballista spam+knight attacks. I think the necessary change is adding friendly damage for explosive ballista bolts. This way, ballistas are slightly less unstoppable, the opposite team has time to recover before the knights come in. Furthermore, it doesn't really make sense how it currently works, where a huge, explosive, missile just phases right through some people and instantly kills others. The only flaw I can see with this is that it requires a certain amount of coordination usually not available in pub games... yet if knights learn to dodge ALL of the huge explosive missiles, I don't think this will be that big of a problem... not to mention, it does make sense that a team siege game rewards coordination and teamwork.
