Personally speaking I loved the old Aatrox he wasn't special or anything just fun to play. The new Aatrox just seems to be in a weird position. He is like riven and Katarina combined, you emphasize on your opponents mistakes of not paying attention and staying in the edge of your q. He isn't good at melee or ranged. He doesn't have any real gap closer besides his "Dash" of his e which is very little distance. I believe that the rework was a good idea in concept but on the wrong champion. Aatrox is suppose to be a character of war, he is suppose to get close and personal. This new Aatrox not only benefits but is the only way to dish out major damage is staying a bit away from the enemy. The new w is a great but they q and e just don't feel like Aatrox. Either riot should revert his old q back and change his e or make his e gap closer better and change out the q for a more close ability. For example they could make his q a little spin move where he swings his sword around like Yasuo when he dashes. When I'm playing Aatrox I'm not looking for someone that wants to stay away from champions to cause damage I'm looking for some blood thirsty, blood boiling, and death loving champion. Which is what the old Aatrox did, he got close and personal. Now I just feel like I'm playing a coward that only goes in when he would most benefits. If i wanted to be like that I would play Katarina and Riven.
For his abilities some ideas that could work and fit Aatrox.
1: Changing one of his abilities to a roar that taunts enemies. Like Warwick's e but taunts instead of fears.
2: Changing his q to some sort of more personal and closer attack range. like changing it into a form of yasuo's spin when he dashes and q or Xin zhao's q where Aatrox would swing his swing in an arc infront of him then slam his sword down in the middle stunning or slowing anyone in the middle of it.
3: change his e to a bigger range but instead you chose the distance you dash. For example 2 Teemos of range.
I am not any expert and I have no idea how this would actually be like in real games this is just my idea of what Aatrox could be like. Aatrox did deserve a rework I just feel like this isn't the kind of style Aatrox should be. I'm also not any form of Aatrox i just took him under my roster to play in the jungle when I saw how powerful he can be. You can do what ever you want with this ignore it, hate it, or report it I truly don't care this is just my idea don't take it to heart.
