Still a little bit confused about tribesmen. What they are good at?

[Johan]

Nothing really.

We do have a civilization value in each city, and also a civilization level in the country that it will naturally progress towards. (lots of modifiers there)

 

[Johan]

Thank you for taking the time for a reply!
So do tribesmen diminish with the civilization level increasing? Or are the two unrelated?

unrelated

 

[Johan]

Ok so from what I gather from your replies they are an unspecialized pops who are not representing a civilization meter within a city.
Sorry to put it bluntly but then why having them in the first place? Unless they are integrated into a game mechanic that you cannot disclose yet, I do not see their point in the pop system and why wouldn't a player want to get rid of them asap? to promote or demote them to a more useful class according to their needs?

To promote them to a more useful one..

However, promoting them to freemen has two costs.

1 - a loss of income
2 - the actual power cost.
