Tilly’s Discipline, the church research card of German civilization, should be nerfed
The German civilization church research card Tilly’s Discipline and the native warrior drummer unit make German civilization infantry incredibly fast. To ensure in-game balance between units, either the native warrior drummer unit should be nerfed or the German civilization church research card Tilly’s Discipline should be nerfed. In this way, German civilization can become a more balanced civilization.
It does already increase the cost of all your infantry by 10%.
Personally, give the choice, I’d just remove the drummer from the German card. That would actually widen the number of allies you’d see Germany choose. Currently it’s always Hanover because with the Drummer Hanover is the best. Maybe it could all you to get a single tech from whichever one you ally with.
Edit: Having said that, I’m not sure a change is necessary here. Germany gets rather limited skirm upgrades so speed is kinda their thing. Tilly’s Discipline has been in the game for years with no changes.
Tilly’s discipline arguably makes German infantry worse, as the 10% extra cost hurts tremendously. You only really ever send Tilly’s discipline for Doppelsöldner which are already a trash unit, they are worse than e.g. Samurai in every metric and still need 3 cards + Tilly’s Discipline + AA to be remotely useful in lategame.
