Good suggestion. (I think it was already made earlier in this thread.)

I also found that markata units do have their uses. For one their small size allows them to swarm larger enemies, secondly they have high defense, meaning as long as they're not under direct enemy arrow fire they tend to bring relatively good results (for 5g units).
For example, in some of my test games I've seen the markata archers stop and handle a charge of a group of knights. This feat was repeated several times in my tests.
