This has been removed from Heroes of the Storm. RightArrow

Mana towers were structures present in Heroes of the Storm. They regenerated ammo, but not as quickly as they consumed it by attacking, so they could not be used as a "defense crutch". Enemy players could easily take them down if their heroes did not defend them, promoting a more aggressive hero vs. hero style rather than a more passive hero vs. tower style of gameplay[1]
