I'd like to see some kind of tower defense built into the game. Maybe in clan wars. Players participate and play a tower defense style game, their results are saved and their progress is compared to other players from that day with prizes being distributed based on that. Your army strength empowers your towers and heros to make it further in the game. Almost like a rogue like. You can pay ori to retry your battle with each try costing more ori that day. Payouts are in denar and crowns. Crown chests guarantee buildings over consumables. Maybe the top players each day getting some kind of invulnerable unit for kingdom defense that provides high defense but can't attack. Or high attack but can't defend.
