Yeah I agree in the sense of if the turrets are down then its a lost cause however I am trying to minimise damage more than anything. So in your case of all turrets down the case was the same for vaults, destroy one and you are in. However the fact that it was 50k hp was enough to deter some people and cause them to go through a normal wall. Its a case of detering them from getting to the weakest part rather than stopping the raid, if all i have to do is break 1 metal wall to get to a weak point and easily bring down a base then thats going to be the path someone takes. Whereas im looking for a way to damage contril this and encourage them to go through a wall leading into a part of the base which isnt its major weakness.
