Stable
Units Technologies Due to the Franks' HP bonus to Knights, the need for Bloodlines is negated (at least for Knights). Knights have 120 HP (the same as Knights with Bloodlines), Cavaliers have 144 (4 more HP than with Bloodlines), and Paladins have 192 (12 more than with Bloodlines). However, since the civilization bonus doesn't help Scout/Light Cavalry (Hussar isn't available), they are at a loss for HP compared to their Knight counterparts. However, this was changed in the The African Kingdoms. The bonus was changed from Knights +20% HP to Cavalry +20% HP, hereby affecting Scout Cavalry and Cavalry Archer lines.
