Alright, Ill move the siegetower about 50% closer, but I reckon I need to make it look good, so I will move the encampment closer aswell. Shouldnt be a problem, this way the attackers can attack the defenders even faster, which infact may generate a new problem, defenders not getting into position fast enough, the attackers can just raise the ladders as soon as they spawn which means they can assault and overtake the walls before the defenders even get over the bridge.
Interesting, I will look into this once I get home, Im thinking of maybe making a barracks or something near the walls, where a part of the defenders can spawn, but then the defenders could spawn behind the attackers, which Ive found isnt much fun. Other way is to move the attackers to all spawn in the encampment, but that means they need to walk for a longer path.
Two ladders sounds about right, on both sides of the gatehouse, to be raised on the towers, as the walls are "spiked", preventing ladders to be used. I will probably add another way in the castle, using a backdoor on the left side of the wall (From attackers POV), which leads into the town itself, and from which the attackers may proceed to the walls, marketplace and bridge.
