Nerf this option. I don’t know… Make limit of day attempts (for example 5 per day). Or make this very expensive (300 gold per hit). Or like shield system – if alliance make Surprise Attack on 2* sector this option turn off on 8 hour, 1* – 5 hour, etc.
Because now this completely absurd. Someone alliances spam and spam this thingy. And war became in pay to win. With poor designed new maps this is ridiculous. Old Surprise Attack system was more better.
