Recruit pattern of computer players takes always same units

[BomSite]

We have released a beta version of an add-on with our own era on the add-on server
Extended Armies Era

For now, the purpose of this add-on is to extend each fraction with units they don't have in the standard era's; example, dwarves don't have a mage or healer in the standard era's, now they have in these extended era's. Basically, it are the default Wesnoth armies, but with additions, and a very small amount of edits, to keep it balanced.

The trouble is that an computer player doesn't recruit all units. It always has his preferred units, that will be used over and over again, although the units are balanced in our opinion.
What can we do so there is more variation in the recruit pattern, and not always the same units are recruited?
Many thanks.

The AI usually picks the best unit to recruit as long as it has enough golds. So you may need custom usages if there is the same one in the recruitment list (fighter, archer, etc). Then list them at the recruitment_pattern keys in the [ai] tag. Well, just an idea, though.

I guess this Era will be popular.

Thanks, I will look into this

Moved to Coder's Corner, that is a better place for AI discussion.

You can also try adding recruitment_ignore_bad_combat=yes.
Another option may be writing a new recruitment stage using Lua AI.
