Seen a lot of overly complicated aatrox change ideas
I'm a p1 aatrox main (previously d5 but got demoted recently I know that doesn't make me an expert but there are not too many higher people who play aatrox) and just want to say that people are looking way to hard into changing aatrox's whole kit and overbuffing his feast or famine playstyle instead of rounding him out by fixing a couple things that just make him feel lousy (while ahead or behind).
Personally from experience I think that this is all he needs to be viable:
-Making the first half of the Q where he goes up uninteruptable would probably fix most Q problems without making the ability unfair. -If they want to keep him squishy and vulnerable to offset his damage+revive then a cleanse on ult activation like alistar's would go a long way to make him feel better to use and not instantly blow up without adding any extra power. -If they want to make tanktrox viable then health costs needs to be changed because currently about 3 items in you lose an entire item's worth of hp using a single combo and you don't heal enough building tank to offset the cost.
I don't believe he needs to be pushed to the side until riot can rework him and would appreciate at least attempting something small such as this on pbe before more drastic measures.
Let me know what you think, thanks.
