The issue with many pro picks that are crap for the rest of us it what they offer pros vs what they offer us. We just want to fight, have fun. Pros are looking on getting the right team comp and power and not just the op cheese pick. It's why Ryze is picked at all, great wave clear, safety with movement and shield and porting around the map.
I think this new Aatrox will sadly always have a problem because of what he offers. That is safe waveclear and safety while building damage. They aren't out for straight up tanks sitting on the front line absorbing damage when you can be Aatrox or Urgot on the front line dealing damage and absorbing it because of shields and healing. I mean they changed his free GA to be a press of a button instead of a reward for doing well.
Look at what pros have done to Tahm Kench for example, all because he has a free QSS. Pros don't pick him because he's strong, great for his ult, they pick him for the free QSS. He'll never have a high win rate as long as this exists and they could nerf it to be a minute and they'd still pick him.
The solution? Make it so he has to stack again to get the GA. Each ability/auto landed on a enemy champ/large monster stacks his revive, 5 stacks and he can revive, like it used to be. Pressing R to live isn't skillful or rewarding.
