Its better than that even. If your sitting on a enemy castle, especially their home castle it seems to draw the AI armies like a homing beacon. Thats my favorite tactic when i have 1 very powerful army and im at war with a nation that i have very porous borders with, i find a castle, preferably his home one, and sit on it with my powerful army. Inevitably he will try to break the siege and bring all his armies that could be rampaging my countryside right to where i want them, in battle with my 1 uber army. Just make sure you have superior forces, on occassion i have been surprised by what the computer can bring to bear and have lost whole armies because they routed with nowhere to retreat. This tactic especially works well when your powerful armies are composed of souped up commanders. In the game im currently playing im playing vanheim with a Earth9/Water9 bless, and im running around with the commander vans and no troops stomping down the enemy, i have almost zero actual troops, so breaking down gates is hard, but if i park 6 vans or so on a enemy castle all their armies will flock to it and be destroyed, and eventually it will wear down most castles. The exception right now in my game would be the machakan home province where they have a dark citadel and i've been besieging it for at least 20 turns. I eventually had to send over a king of elemental earth with a gate cleaver before i was doing any damage to the gate.

p.s. I've also come to believe its not always bad to have an enemy castle you can besiege forever without being able to conquer. The AI seems to take into account how many wars your already in before declaring war, as long as there is somebody still in that Last castle you are still at war with them and the other AI teams will be less likely to declare war. This gives me time to actually rebuild after a damaging war without having another AI immediately declare war on me.
