AP vs lethality

[Apázlinemjó]

I'll use Bataroas then.

Still, it'll be helpful to know if and when AP becomes more useful than lethality, because I plan to conquer the map with Arverni. The answer can help me determine how much Gaesatae I should use against the enemy. >_>

I think, AP becomes more useful against heavily armored units, like Thorakitai, Hoplites, Triarii, Medium -> Elit Phalanxes and such.
