Nerf Structures to take 25% of normal God damage starting 1 hour after last clan log in.
So if i log off in middle of a raid, you have 1 hour to summon a God. (with the 1 hour craft time now for tokens, it means you would have had the token either started or done before i log off). People could still use bombs to raid me, but it may take more time, and based on my building skills, i could make it harder to offline wipe me.
Just an idea, open to comments/tweaks.
