They eat up all my Garrison resources...I just finished the first zone and upgraded my Garrison to Level 2. I have only built Barracks and Lumber Mil (have 2 small building empty cause I have Mining-herbalism). Still, just all my followers to missions I spend almost 70-80% of my resources. My Lumber mill just created, so this may help a bit in the future, although Lumber mill offer 20 GR every 4 hours and Missions take 10-20 GR each and some of them are 1 hour, others 1,5 hour...
Am I doing it wrong? Should I just focus on 2-3 followers at a time and not putting them all on missions every hour?
