The conversation started like this:
----------------------------------------------
Message from Yaroogle: "It's actually a good thing that there isn't a hero with starting infinite ammunition..."
Message from IronAxe: "But there are heroes with tents that have INFINITE medical supplies. And this also has its quirks, as VDV pointed out in the Tournament Troubles thread."
-----------------------------------------------
Here, Kamikaze immediately jumps in, talking about ramming with some magic and abilities, even though the topic wasn't about that. As I understand it, Yaroogle's point was that infinite ballista ammunition should be considered a bug. Then, there wouldn't be any hero with infinite ammunition in principle. I countered that there are heroes with tents and infinite healing. I'm explaining all this specifically for Kamikaze.

"I think it's perfectly normal for the ballista to have 18 billion arrows. The soldiers are constantly supplying them."

What soldiers? Are you hallucinating? Have you seen them? Where do the infinite soldiers come from? Or are you saying that a couple of soldiers are constantly supplying 18 billion arrows? Won't they get... tired? That's why many people didn't see any soldiers, but instead saw the ballista window where the shots are counted down to ZERO, and then go into the negatives! That's why many people think it's a bug, without suffering from vision problems, and not seeing any running soldiers supplying arrows.

"After all, with the Ammo Cart, archers don't run out of arrows, and you're not against it... I hope."

That's exactly what they're not against, because with the ammo cart, both archers and the ballista behave adequately; they don't run out of ammunition, BUT THE SHOTS DON'T GO INTO THE NEGATIVES! Here, you should be looking for soldiers; they should be there, but I still don't see them.

In my opinion, I have a different view on this. In reality, we don't know what the developers intended to do (maybe someone will find details in the documentation). Maybe they did want the ballista to have infinite ammunition, but the programmers messed up and mistakenly attached a window with 24 ammunition to the ballista. Therefore, we can argue endlessly, but no one can say for sure whether it's a bug or a feature.
