When is Riven going to be fixed?

There's no excuse for the state Riven is in. A mentally handicapped chimp is able to play Riven, feed, and then win by flashing into a carry and killing it in 2-3 seconds.

I just had a game where I destroyed Riven in lane as Cassiopeia, one of the hardest scaling carries in the game. Riven kept ulting and failing to get in range of me, or trying to Q into me, but failing and taking a lot of damage for it. I killed it four times. It killed me once with a flash combo from 100% at level 6, and missed two flash combos after that.

In a team fight, it tried to chase me down, and I kited it and brought it to 70% health. It then backed off and our Thresh hooked it. I went in for the kill. Once hook was over, it flashed into me. I flashed away before it stunned, and ulted it in the face and kept tunneling damage. It got out of my ult at 30% health and killed me with 15-20% health left, and Thresh coincidentally died just from AoE damage, as he tried to flay it off of me. I was sitting at 2.7k health with an Armguard and Revolver. Riven only had Hydra, Maw, and a Ghostblade without the active.

This isn't okay. Once upon a time, players were punished for playing poorly. Riven prevents that from happening, and often even rewards bad play by turning lack of awareness into a double kill when something tries to gank her.
