Sgt. Hammer is one of my new favorite heroes from Heroes of the Storm. He's basically just a siege tank. He operates much like siege tanks from Starcraft. His long-range attacks are devastating in siege mode, but he takes on more damage faster in siege mode.
The trick to using Sgt. Hammer is to keep dealing damage from a distance. He comes with a number of tricks to keep your enemies away, including a wall you can summon, and the ability to move while in siege mode.
