Can we do something about Graves?

Ever since Riot nerfed his E last season, he's been stuck at around 47% win rate. Granted, Graves was indeed disgusting in late season 5 and early season 6 back when his E was legitimately overpowered, but part of that was also because Armor Penetration was broken for snowballing with him in the mid game back then. Now that the far healthier Lethality has replaced Armor Penetration, I feel that Graves could use a slight buff to bring his performance up.

I'm not saying revert his E nerf or anything like that, but maybe a tiny bit of base health or health per level could do him some honest good. It sorta worked when you did it on Xin Zhao after those devastating mega overnerfs he received in patches 6.4 and 6.9. Xin's a bit more balanced now (though still not that good), so maybe it can work for Graves too?
