CRUSADER KNIGHTS

If they were trainable units for crusader civs such as Teutons, Franks, Britons......How would they impact game what do u think. It's not written there but u Can train them at Castle.
Their stats 100HP 4/4 Armor Attack 18 Attack rate 2 Speed 1.2 Line of sight 5

You can train them at Castle for cost of 80F 50G (It's possible only trough triggers so don't know if they Castle or Imperial unit) As of now neither Civ bonus such as Franks HB bonus or Teuton Melee Armor bonus apply to them Also bloodlines does not apply to them.
