Ideas for WW1-style Imperial German divisions

Hey all,

I and a friend are doing an ahistorical multiplayer run of Germany and Austria-Hungary. I want to play Germany and build divisions inspired by WW1 Imperial German army setups (so more flavor than pure meta but still viable).

I'm pretty decent at the game but not great, and my friend is still fairly new.

What I need mostly is:

• Good early/mid-game division templates for Imperial/Prussian Germany.
• Suggestions for doctrines for the playstyle (as I am not familiar with the meta)

For reference: not going crazy with min-maxing, just trying to keep it fun and semi-historical while still being effective.

Thanks!
