This should only be enabled when all clan members are offline, because online raids are almost impossible because of how easy it is to replace building pieces and trap in raiders.
I’m of both minds about some mechanism for auto repair, be it a bench with a worker that repairs at a rate or whatever. I get what you mean by it being a survival game, but I also get what bugs people about some pvp behavior. I think the survival aspect is the pve side of the game which pvp also must do. I think the survival part could be enhanced if some things were mitigated for pvp.
I think auto repair for your building is a good idea its very hard to fix things definitely if you have multiple structures over the part that you want to repair but then auto repair should only be accessible after raid time
Not really just use your hammer during raid time and fix everything in one go after raid time it would be very op to fix everything in one go while ur getting attacked
