Don't forget you can order your men around, just like on a normal battlefield. My sieges work great tbh. Only one in 50 sieges have people not climbed the ladders or siege towers, and I realized I needed to give them an order, and they climbed up...The last major update we got regarding sieges was the upcoming Keep battles, but we have had no mention of it in the latest updates and siege towers and ladders are sill pointless to use. Defenders still swarm the ramps and when the tower is pushed to the wall 1 guy is able to drop the ramp. This needs to be improved substantially as Siege Battles are one of the best aspects of medieval battles.
