Thank you! I couldn't test the game enough during game jam so current balance is not good. As you said, giving % stats from tree and flat ones during training could be better. Fame requirement is also nice, some of critical upgrades may be unlocked with this. For the labor spamming part, I think there may be some penalty if you pass Help encounters, they may reduce your fame if you skip them. As you are more hero, you will get more responsibility and people believe in you so breaking that promise should be bad. Encounter count also can be increased with fame instead of from skill tree.
