hi i have a few ideas to make World of Warcraft Universalis more elaborate. I thought of sub type for soldiers units.
I have made a list of unit groups.
1, light infantery that can build at faster rate. but less strong in combat. like zombies, murlocs

2, soldiers with bow and arrow or crossbow or a blunderbuss. who are less strong in defense but have a higher fire number where they do more damage to the moral.

3, soldiers on a horse or other mount or centaurs and flying creatures such as harpys or dragons they have and high shock and normal damage but are less strong in the defense

4, heavy infantery such as giants. it takes longer for them to be made but stronger in the defense. and have a better moral. do more nomal damage.

5, siege vehicles such as catapult or steam tank are suitable for besiege forts.

6, magic users such as priests or mages.

I thought with these units you can make several soldier types in countries that consist of multiple races such as the burning legion.

I also thought to make the magic types into ideas and that any country can only unlock the magic type if it has the same faith.
