Is Volibear based off of Ursa from DotA?

I've been playing some DotA 2, to take a break from league, and I came across a hero called Ursa. I instantly loved the hero. but he stroke me as very similar to Voli, both skill wise, appearance, and play style. Even though I was playing DotA 2, was in DotA as well. Let's look at the facts:

Both are bears Both were armor Ursa q is an AoE slow that does damage around himself, sound familiar? Both scale off of attack speed Both tend to build tanky (Ursa not always, but usually has a bit of tankiness) Both get damage from hp Both are great duelist Both have abilities that increase in power after basic attacking multiple times Both are basic attack reliant

The connections are plentiful, and all of them are strong. I'm not sure if it's just me, but the same people who made League also had relations with the creation of DotA. They ofc have their differences, but seem soooo similar, it would strike me as strange if it is a coincidence..

Thoughts?
