CRPG Siege - BI Stone Keep

This is my first attempt at creating a siege MP scene for CRPG if any huge issues come about from its design I am happy to make changes in order to fix them. Layout -Attackers spawn in camp out front of walls -Defenders spawn throughout town (none placed on the top of walls but many within easy access of stairs) -2 Gatehouses one front and one rear with portcullis -2 Siege Ladders one front and one rear -1 Siege Tower front If the attackers can successfully take the walls via the siege ladder or tower out front they will be close to the gatehouse if the front gate is opened the attackers will have a quick route into the towns front street. Closing the gate will be the first order for defenders (as can be imagined the gate being open allows the attackers to spill in with greater numbers), if unable to it is not hopeless to defend but will mean that the centre keep is going to be under heavy pressure. The rear gatehouse will likely not find as much pressure in matches but if some attackers are one horseback or can catch the defenders off guard it is within a moderate distance on foot from attackers spawn but should be interesting. Here are a few screens taken to provide an idea of the layout
