Free Riven this week
Perhaps a bit too strong for such a durable champion though...
>Low-cd escape mechanism, it's like Shen's shield and dash in one.
>High innate mobility @ 325 base MS.
>A second gap closer in her Q.
>Steroid damage and a finisher from R, Garen-style but with more range and AoE.
>Plus a small stun to help dish out maximum damage.
The only downside I can see is the fact that she scales off bonus AD, but even if you build her more on the tanky side, she's still a visible threat. I wouldn't be able to change anything on her though, she just feels right the way she is.
