I would have liked to see more leader traits in BTS. Especially with the new features.

I am no professional but this is my latest, of what I am sure is flawed, attempt to come up with new traits:

Totalitarian
-20% Hammers for Spy Production
No Upkeep for Police State
Cheaper Jails and Security Bureau

Diplomatic
Automatic +2 Diplomatic Points (Wait, this wouldn't work on mulitplayer...)
Missionaries always work

The geniuses at Firaxis could probably do better.

I had a few thoughts on this too;

Militeristic
+20% military unit production
Double the building speed of barracks

Intellectual
+5% research in all cities
double building speed of library/observatory

Enduring
-50% wartime weariness
Units start with Guerilla I and Woodsman I

Economic
+1 trade route for your 5 largest cities
double production speed of bank

Dominant
In combat, when attacking and your odds are at 85% or higher of winning a battle, it automatically becomes 100%.
When attacking and normally facing odds of 50% or below, your unit receives a +10% attack bonus.

I just realized that the Diplomatic trait would not work well on multiplayer so I will definitely have to revisit that.

Hasty
Units cost 30% less hammers to make
Units have 30% less strength
melee units start with blitz

Productive
Buildings, excluding wonders, are built 5% faster
:mad: from slavery lasts half as long
chopping yields +50% hammers

Progressive

+25% science production
1/2 cost of libraries, laboratories


Agrarian

+1 food on all squares making food
1/2 cost of grocer, granary

Strategic
Hill, Forest, Jungle, Fort and City provides an addition 25% Def
Double Production of Wall, Castle

Tactical
Siege Unit and Armor Unit starts with Barrage 1
Barrack and Stable provide one addition exp

Religiuos
Double production speed of missionaries/monastery
unlimited number of missionaries can be on the field at a time.
