Question about weapon selection AI

[Hoki]

I can't figure out how the weapon selection works with BC AI.

I create a custom battle with 1 unit of roman spatharioi guards vs some heavy cavalry. When they approach charge range, they'll stop, swap to sword, then charge in and attack cavalry with swords.

And then sometimes they'll do the opposite against infantry, attack infantry with spears. You can see how these are bad things.

Am I doing something wrong or is the AI just random with it's weapon selection?

i have the same issue,but some times i have them on defence mode and charge.the most times when they are on defence mode the use their spears.but that doesn't always work.

The M2 engine doesn't handle infantry with two melee weapons well.
