After going through so many threads I am still confused whether the defense buildings really help or they are useless.
If defense buildings help us-
1. Do they protect us when someone attacks us or when someone robs us?
Or they help in both?
2. How effective they are as compared to our defense weapons and defense skill points?
If they're useless -
1. Then why they are in the game?
Why Gree can't shift them to the 'Decoration' section of the game?
