Hey a Bard class would work great in this game, either for helping the workers out or the soldiers out. An idea for the Dev’s or Modders 
This is just a basic idea.
Bard:
lvl 1- Melody: They walk around and sing keeping the happiness of villagers up.
lvl 2- Inspiration: They inspire workers to work faster and longer.
lvl 3- Battle Song: They sing, giving a buff to soldiers for damage and speed.
lvl 4- Heal Song: They heal the wounded.
If y’all have more ideas, throw them out.
