I would like to suggest a permanent 100% garrison troop refund when disbanding the troops. Because you only receive 50% of your spent resources back, very few people who have invested heavily in their garrison will ever change races. For this reason I think it is stopping people from experiencing all of the races to decide which is their favorite. People who disband their garrison troops have to spend all that time rebuilding their wall which I think is payment/punishment enough for wanting to experience another race to its fullest. Thank you for your time.
