One of the ways that M2TW differs from RTW has really messed with my game style. It's this one: When you're besieging a city/castle, and you take the gatehouse, you no longer are able to capture the towers. Technically, you take the walls once you've broken through the gate, but the towers will still fire on your units right below. This is true even if you've knocked out all units nearby, and have a unit sitting right between 'up top'.
This is particularly frustrating if you're trying to melee nearby units on the walls, etc. because you end up losing more from the towers than fighting the other unit.
Does anyone know a way to actually capture or disable the towers? Or do you need missile siege equipment to destroy them?
