HRE needs a rework, post ideas!

HRE is pretty useless atm, please post some ideas to give them some help.
i think the following would be nice and fits well with their themes:

  • buff landsknechts
    (not sure how to do this best, maybe just more health? Infantry focus)

  • replace outpost with a stone fort
    (like rus fort but made out of stone. Defence focus)

  • new unique unit teutonic knight
    (mounted knight with the inspire ability of the prelate, and posibly a fear debuff for enemies?most other civs have 3 unique units, why not the HRE! Religious focus)
