Just did some tests in the editor. Celts have the 10th best imperial age knight line in the game with the paladin upgrade

So stop saying it sucks. And Celt players dont be afraid of using it more!

Rank (Equal numbers not cost effectiveness since knight line in imperial is more about pop efficiency)

1) Lithuanians (Best depending on relics) 2) Teutons

3) Franks

4) Persians (Generic paladins but Anti Archer bonus)

5) Cumans (Generic pals but Faster)

6) Magyar (Generic pals but free attack upgrades)

7) Spanish (Generic pals but no gold upgrades)

8) Huns

9) Bulgarians

10) Celts

11) Malian

12) Byzantines
