Why is Vayne being pushed as a top laner by riot?

Yes this is rage post about .

14% health true damage + press the attack which is super easy to pull off . Tumble is on low cooldown gives insane damage on its own and is enough to ensure that silver bolts and pta are proc'd on every short trade. 9.15 buffs to her stun is now makes sure you will lose 1/2 your health bar minimum before you recover. She can disengage melee opponents with condemn and win all trades. Her kiting ability makes sure an ability based fighters will not land anything like Aatrox. The ultimate makes extended trades impossible to deal with. Also the jungler will come top and make sure she gets a lead on to you even if the jungler doesn't kill you (denied cs). My anger is not directed towards the sadistic meta slaves that abuse this bias towards Vayne but rather riot which continues to promote her in this role as she is a toxic and is the most tilting aspect of the game. I means shes an option in the top section in champ select.

Possible fixes: -Nerf pta's damage from 40-180 to 30-160 and decrease the increased damage taken from 8%-12% to 5%-9%. (Big nerf yes because this rune is broken as heck and is the strongest rune in the game) -% health true damage down to 11 or 12 % from 14% at max rank -Increase tumble cooldown by 1 second at all ranks and increase mana costs to 35. -Revert 9.15 buff (wtf riot?) -Reduce movement speed by 5 -Remove bonus AD from R

The problem is that vayne should be made horrible top and kept balanced on the bot lane and there has to be some equilibrium. Either shes too weak and is not played bot or shes too strong as is abused top lane against melee matchups. These suggested nerfs are meant to gut her obviously but I'd rather have a champion like vayne slightly average than have this level of toxicity. She is absolutely disgusting in her current state and is a justifiable reason to run down mid.
