What are you expecting in the last 2? It seams reasonable to me.

You have double his archers, and a 1:3 ratio of ballistas to archers? That was a guaranteed wipe out anyway.

The first one is a little different, but I think it is more realistic for a troop like that to die against your defense. I think both are reasonable outcomes.

Your defense is ridiculous, so why would you expect someone looking for an easy kill with ****ty ass troops to beat you?
