Idea on town hall and castle: defense ability and troops for town hall
Town hall and castle have defense ability. Arrow attack for town hall and cannon attack for castle. Damage will be half of the highest level archer tower/ cannon of the player's village respectively.
Also allow players to add troops to their own town hall. Capacity will be two times the town hall level (example level 7 town hall will have 14 troop capacity). Range will be three tiles (or whatever longest range available). Will stay in that range.
