1. The purchase cooldown seems to be a big nerf to Landschneckt. Have they been given anything to compensate for this? 2. Making all early siege units require iron seems like a big nerf to warmongering. Has anything been added that makes warmongering more attractive for players who get cursed with no iron? Also, does it really make sense for catapults and trebuchets to require iron? They were made entirely of wood and rope after all. 3. Doesn't giving rocket artillery anti-tank as a promotion explicitly buff them against the primary unit intended to counter them? Or did you just think the counter was too hard in this case? 4. Is there an image of the tech tree? The thing I hate most about vanilla is how much of a mess the Industrial and Modern tech trees are, with aircraft coming before modern warships or any other of the myriad things that could shoot them down that existed before they were invented (AA guns were just massed machinegun batteries after all).
