His early game is not as strong as a lot of tanks, but do not underestimate beetle build. Once I hit level 13, I can crush anything and anyone. Buildings, camps, minions, stray Vallas, you name it. After 16, I can 1v1 any melee hero, and have given a number of Garroshes and Muradins the surprise of their lives. The trick to playing Anub, especially early game, is to use a full hit and run style.
