Build Number: 18.18178
When the Taowu (Heroic Chinese MU) is in its charge animation, clicking on an enemy unit results in the MU stopping just short of its target to use a regular attack, which wastes the knock back effect and damage. Same thing when you click on a building.
To use it properly, you have to click past an enemy army, and for buildings, click right on the ground within a few pixels of the building. I don’t mind microing the bowling ball against units, but trying to charge a building shouldn’t be a hassle, especially when you group attack a fortress with your army.
I think changing the logic of the ability, and making what you click on be where the Taowu wants to center itself, would make it work as intended.
