Under such a situation that there are no obvious gaps in participants, it is not difficult to defend a closed city, after all those defensive structures and thick wall can play a great role to prevent the city from being occupied by enemies. During the process of the offensive camp attacks and managed to occupy a city, sorts of siege weapons play an irreplaceable position, that is a nightmare of defensive camp.

Siege Engines, which is always placed in the front of the gate of opponents, can cause deadly damage to gate. In general, personal can cause only 100 damage to a gate, while engines can cause up to 5,000 damage to it. There is no camp jump into WvW offensive tasks without this kind of vehicles, which sold at 0.2 Guild Wars 2 Gold each.
Robot who is of high flexibility, is also a weapon used to siege which is able to cause outstanding damage. Certainly, it also sold at expensive price, you often need to spend one GW2 gold to get one. If there are several robots in your Guild, I think it is very easy to occupy city.
