It's my trademark.. kind of like ATS with invisible wallsTouche.. :)
Perhaps make a barrier to stop people from climbing the hill to the left of the left gatehouse. Would make it a tad easier to defend.
Agreed. ALso, what purpose does the gate serve if people can just as easily ladder up the wall?
Perhaps make this a leveler activated gate with some way that defenders can pop out without having to open the gate?
Basically you need to make the gate worthwhile to attack, some sort of benefit to having it there. If taken should provide an advantage for attackers.
