I did a few searches before writting this can't fidnd it so I will ask.
I have seen the term having a closed gate or open gate a few times.
And I am aware that there is an option in the Rally point to Have or NOT have the gate opened diring an attack to send out troops.
So is that toggle what having an open or closed gate means? Or is there a specific location to close an open a gate? And if the gate is closed will traps and abitis and archer towers still defend you against raids outside the walls?
