Change shield requirements
It would be nice if they lowered shield requirements to 35%, or gave a shield after a certain number of resources were stolen. That way, we couldn't get attacked 4 times in one night, like I was.
Attack 1: 2 lightning spells, 5k elixer, 235 dark.
Attack 2: 39%, 15k gold, 80k elixer, 50 dark
Attack 3: 35%, 137k gold, 71k elixer, 250 dark
Attack 4: 3*, 265k gold, 140k elixer, 890 dark
And I was only offline for 5 hours.
Another suggestion is to sell shorter duration shields, so we can protect our resources while sleeping or at work.
