Most defenses seem to be focused on attacking anyone close to them. I'd like to see the opposite, as a much needed HG counter. Something that can only attack at a minimum of 5-7 tiles away, maybe even more, but up to say 15 tiles away, in a full 360. Kind of like a mortar, but with direct steady damage. A sniper-like tower that can only fire far away, at the standard 15 speed (3 shells/2 seconds), hitting a single target. Somewhere more than what a GT hits for, but less than a standard cannon, maybe 25-33 damage which is about halfway between the two. At close range it would be completely useless, but it would help a lot with troops that can stand way out of range of everything else and pick it off. You can put literally any building in front of a gun tower, and an HG can snipe that building without the gun tower reaching the HG, if the shoreline is extended even slightly. Most buildings can currently be sniped with a cannon behind them as well, especially if there's a wall between the cannon and the building. While current defenses are effective for short-range troops, and even normal gunners, we really need some sort of long-range counter. And by limiting it to ONLY long range, it wouldn't be OP. As soon as you get close, it becomes useless.
