It is certainly not nice to see something you have just built destroyed. The grinding itself is not the frustrating part. I used to listen to podcasts or music while mining. I spent days in the mine and even created whole tunnel systems under the map. Now that's no longer possible because of the digging zombies and the screamers that spawn every 2-3 minutes. I then have to interrupt and fight the screamer horde, and that's the really frustrating part.
It's getting harder and harder to maintain a semi-peaceful play style. Everything is now about killing zombies.
Even with all the traps, you are not completely safe. One explosion and all the traps in one area are destroyed. Then there are the radioactive cops who can destroy the blade traps very easily with their spit. The only traps that remain are the dart traps and they consume huge amounts of iron.
The frustrating thing is that you don't need a base. I have also run around on the street and fought the zombies on foot. It was easier than building a base and that's the frustrating thing. A base should give you an advantage.
Since the demolishers have been in the game unchanged for a while, I doubt that any changes will be made.
This is certainly a convenient way to play but it is also the least creative way. You're basically playing the game like a loot shooter and throwing the part of the game I love out the window.
Good for you but not for people like me.
