Tumble- short range and doesn't go on cooldown until you AA or the buff wears off

Condemn- if they don't hit a wall, you just push them back a pretty negligable amount

I agree with Steakasaurus that if a vayne is getting away from you that easy, you must have screwed up badly (like running between her and a wall)
