Abathur is a extremely flexible hero ranging from soaking and laning to soloing keeps with powerful locust and murdering heroes with mines and a slap. The thing most people don't know about abathur is that he goes from a team helper (damage), laner (soaking OR buffing and pushes with waves), which is general low to high level abathur game play. Not that this style is bad, its just most common, I see very few people who unlock the full potential of Abathur. because he goes beyond that: he can backdoor, destroying forts swiftly and easily, heal the team, or even solo a core!
