Siege engines like catapult, trebuchets and other siege weapons will be very useful in the bigger pvp battles, they can do heavy damage to players, but they are best against buildings, like the Battlekeeps in Border Kingdoms. If you want to get in to a battlekeep or a city made by NPCs you need to take down the walls/ gates first with siege engines, there is no other way. The siege weapons can also be used to protect your city or battlekeep from other players or NPCs.
Siege machines can only be build by a crafter. The siege engines can be build on the battlefield, but it takes several minutes to build one, and you can only build a set amount per day per individual. Siege engines will move slowly, and you will need to mount them and fire from the "seat" of the machine. The Siege engines will also be expensive and quite easy to destroy.
