This week possibly my top one hero gets the honor. The brutal hard carry and Roshan slayer, Ursa.
Ursa is a beast, literally, dangerous from level two and throughout the entire game. With insane attack speed and damage, he is a hero you want on your side.
He is my most successful hero and I will continue to use him for a long time. Even though he is kind of “cheap” and “easy mode” if played correctly, but he is also easy to counter if you know how.
