Restriction of Attacks by big players on little players
Could a restriction be put on attacks, such that you couldn't attack someone if you were more than a certain multiple of their size. I don't know whether this would be better as 1.1, 2, 10 or something else.
Recapture of a captured castle within a certain period (e.g. 7 or 10 days) would be allowed.
I know this would change the game a lot but would allow small players to grow without the fear of the big boys.
Support of an ally under attack could still be sent of course.
What do you think?
