Aatrox Nerfs
To start this rant off, I would like to say that Aatrox does not feel like a GOD KILLER anymore. He isn't even a minion killer for that matter. Patch 9.18 (if you didn't read the notes yet), nerfed Aatrox's mid-game lane sustain and nerfed his ability to push waves by giving his Q 40% damage to minions. It used to scale from 50% to 100% based on levels.
Disclaimer: I'm a low elo player (oops) and my opinions are probably wrong but who cares I want to get them out there anyway.
Let's start with that Q nerf: Riot were hellbent on nerfing Aatrox's ability to stay relevant in the mid-game, starting with cutting his ability to snowball. Aatrox's extremely long cooldowns and low mobility early game already had made him considerably weak early game. In order to get ahead, you had to hope to god that your opponent would be dumb and wouldn't dodge your Q's. It's obvious that Aatrox's strong point was that if he were to get ahead, he could snowball to infinity (at least in the mid-game). This is IMPOSSIBLE to do now and it feels like his personality was cut by his in-game performance. He's so much weaker and there are so many more champions that scale better than him, start better than him and have a better late game (Riven comes to mind). Recap: Aatrox no longer snowballs. If he does manage to get ahead, it's tough to stay ahead.
The passive nerf: Aatrox is a drain tank. He needs healing. Healing on fast champions is hard because you never get to passive hit them. Aatrox has absolutely no healing against a ranged champion or a mobile champion after 9.18, and that really sucks.
He isn't fun to play anymore :( his winrate got lower than the sub 47-48% winrate he already had in high and low elos. Pro play isn't the only play :(
