He would be still nothing compared to a well fed Nasus with Thornmail. Thornmail would return a ridiclous ammount of damage back to him and Nasus would slow his attack speed to nothing making him useless.

If you ask me Ursa would be either kited to death, exhausted to death. And he is easily countered since he deals only physical damage and is very reliant on his ultimate.
