A simple suggestion regarding Aatrox's W (Blood Price)

I know you (Riot) want to rework him one day. But before that, maybe we could give Blood Price a buff.

Blood Price feels extremely underwhelming especially in the later stages of a game. It is your only good source of damages in lategame but unfortunately, I almost never use it in teamfight or in 1v1 because the ennemies have so much armor and health that I prefer to simply be tanky as possible by using Blood Thirst.

And because Blood Price deals a too high amount of true damages to Aatrox himself, even in 1v1, by midgame / lategame, I prefer to try to outsustain the ennemy bruiser / tank with Bloodthirst.

TL;DR : the longer the game goes, the less I want to use my only source of damages.

So why not give Blood Price bonus armor penetration only on the third hit ?

=> It will not increase Aatrox effectiveness against squishies that don't build armor. => It will give Aatrox a reason to use Blood Price instead of Bloodthirst when fighting an ennemy bruiser / tank beyond laning phase. Aatrox is supposed to switch constantly between Blood Price and Bloodthirst but it is NOT the case right now. => armor will still be effective against Aatrox because only one third of his attacks will have bonus armor penetration.

Exemple : each point in W gives Blood Price 7% of bonus armor penetration (up to 35% at max level).
