Steam Badge Design

Aside from the gameplay, I would also like to contribute a feedback that the design of steam badge is poor. The different working type of villagers should not have been indicating the hierarchy from badge level 1 to level 5. My idea is that it would be great if the level aligns with the age you are in
for example: level 1 dark age; 2 feudal… 5 post-imperial. It seems look more interesting.
