Overdone is a gamemode that changes every hero in one way or another, whether it be base stats or a workshoped ability.
If you want to see all the changes go to this google doc to see them all: https://docs.google.com/document/d/1O4CyPWUcIFhGMzKNSdCI4ffV98yncVSeaEwwQkSFzVk/edit
Other than that thank you for at least looking at my mode for 5 seconds.
UPDATE Bastion is undergoing maintenance, because his no self-damage workshops, is not functioning properly. Just know you will need to heal if you decide to rocket jump as Bastion.
