I kinda agree with OP. While i also understand u cant magically appear in the castle with your army. Still its much harder to get to def sieges. Which i really miss. Its really rare that enemy comes to siege town/castle where u are at that moment. How about if your castle or town is besieged u can play that battle as one of the soldiers. U can choose which one. I dont care that i cant help with my army just let me play as castle garrison so i can experience def siege battles.
